Why Renting Computer Equipment Is Better

By and by our continuous technological advancement has improved the standards on what we call the “good life”. A lot of us are now enjoying a life that is more efficient and orderly thanks to the machines and devices that is developed by geniuses all around the globe. However, as technology progresses, the prices of the gadgets and gizmos that we want to make our lives easier gets more and more expensive too. Some examples for these are computer equipments.

Computers and relative devices could contributed hugely to the fast growth and development of a business, which is why nowadays you would see that almost all companies would include them as their asset from the start. A lot of people would say they prefer to buy their own computer devices as a long lasting investment. However, there are some cases wherein computer equipments are better rented that purchased. This is especially true for starting companies who wants to use their capital wisely. This is because if they purchase their own unit, they would have to worry over the budget for technical support. But in rental, a good and reputable company would be able to provide free technical support so that if the renter encounters some difficulties they could just give their rental service provider a ring, and they would be responded instantly.

Also, in urgent situations where you would need your devices transported to other places such as for conventions or temporary moves, it would be better to count on a trustworthy computer equipment rental company than to load your mechanisms in a car and risk damages to it. It reduces the waste of time, energy and finances in the transportation, and it also eliminates the possibility that you might have to get your machines to a repair shop because of some break it may get during the transport.

These are just a few reasons why renting a computer equipment might be a better option. Aside from computers, there are also other technological equipments that are available for rent. Through rental companies, it is now possible to get our hands on these useful tools without worrying too much on the purchasing price and on the cost of its break and tear.

What are Current Transformers?

Electrical equipment that provide a flow of current in the secondary circuit that is directly proportional to the amount of flowing current with its principal circuit is called current transformers. Current transformers are the ones responsible in calculating the current so that the operation of power grid is monitored. This type of electrical instrument is widely used for the purpose of safety in any establishment that utilizes electricity at considerably large amount of voltage.

For metering and protective measures, current transformers are used. This equipment is very important among companies within the giant industry such as electrical power industry. The safety is guaranteed and made even easier through this tool.

How do current transformers work?

Current transformers cut off voltage flow securely so that only lower amount of current would flow, allowing the overloading of electric supply be minimized. This equipment controls electric current by allowing the voltage flow to pass through the windings of wire being wrapped around the well-insulated toroidal core. Current transformers measure the flow current, giving the necessary data to the reader so that the power being used at particular time and length of time would be monitored.

There are some factors that we also need to know about current transformers.

InP Technology To Be Used in Agilent Technologies’ Chipset for Next-Generation, High-Bandwidth Oscilloscopes

Agilent Technologies Inc. had just very recently revealed their technological advancement in the next-generation, high-bandwidth oscilloscopes—the new chipset that could make possible the production of oscilloscopes with true analog bandwidths greater than 16 GHz.

This new chipset will be using indium phosphide (InP) technology. The company claims that this would prove to be better than digital signal processing (DSP) and frequency domain interleaving, or also known as digital bandwidth interleaving or DBI) other bandwidth-enhancing techniques because it doesn’t cause a lot of commotion that hampers the performance and measurement accuracy of the oscilloscopes, a concern that usually comes with the aforementioned techniques. It is somehow also better than the silicon process technologies which are commonly used in the present, which are not truly able to extend the analog bandwidth above 16 GHz range.

The InP technology is said to actually enhance the capacities of the company's InGaP HBT (Heterojunction Bipolar Transistor) IC technology, yielding high-frequency capability with transistor switching frequencies up to 200 GHz. Aside from that, this technology also has better material properties than that with the gallium arsenide (GaAs) process formerly used by Agilent. This is because InP technology gives higher saturated and peak electron velocities, higher thermal conductivity, lower surface recombination velocity, and higher breakdown electric field, which makes the expansion of the present limits in true analog bandwidths.

It is also said that the InP technology enables oscilloscopes to have significantly flatter response at high frequencies, higher measurement accuracy because of the low-noise, nonconductive substrate, and higher reliability due to lower power consumption than what we have today.

It seems that the 16 GHz limit would just be the first step for the company. According to Jay Alexander, vice president and general manager of Agilent's oscilloscope organization, "Our first oscilloscope family offering this new high-speed chipset will start at 16 GHz bandwidth." They would be introducing this high bandwidth family in the first half of 2010.

These tool must be configured with up to four elements into 760301 (1 Element), Yokogawa 760302 (2 Element), Yokogawa 760303 (3 Element), and Yokogawa 760304(4 Element).

Electricity Safety Tips

Electricity is a powerful two-edged tool. While it’s true that we have been highly benefited by its energy as it is used in our everyday lives, it also has a great potential for destruction when we don’t exercise care and caution around it. So here are some of the basic safety tips to follow in order to avoid electrical accidents.

One main thing you should do is to make it a habit to switch of unused appliances or equipments. This is not only a safety tip but is also a suggestion that could help lessen consumption of energy. Also, if you notice that a cord is unusually hot, unplug it immediately from the outlet, and then have your qualified electrician check and mend any faulty wiring as soon as possible. If possible avoid plugging on areas where wires can get tripped on. And make sure that your power cords are not faulty or damaged, or if they are, let your electrician do the proper repairs.

See if there is discoloration or burn marks in your appliances and refrain from using it without having it checked by a competent technician first. One thing you should also remember when buying your appliances is to make sure that they conform to the safety and quality standards. Do not buy devices that are cheaper, and check if what you bought have been recalled due to manufacturing problems. Follow the instruction manuals when using them. It would also be wise to conduct a regular PAT test for your equipments. This test is required as a safety regulation in workplaces.

Electricity should not be taken lightly just because it has been a part of our daily existence already. Even one act of negligence might cause unexpected tragedies. Following these safety tips would help. But being cautious is still the best safety procedure.

Facts about Insulation Tester

When doing projects such as home renovation, it is important to use insulation tester. The reason is that your overall safety is ensured by using such device. Prior to adding soundproofing material, major repair projects where electrical system quality is not known, and installing wallpaper, insulation testing should be done. Leaking current would result if there is insufficient insulation. Obviously, leaky current is the common culprit of hazardous events such as fire.

Insulation testers are one of the easy-to-use technology products; it can be used by a novice. This product is usually performed even without the help of a technician or an expert.

This product works with the application of DC voltage to the insulation system. The current that flows through the DC voltage is measured. Then, the results of the test would tell if there is or nothing wrong with your home electrical system. Current leak is accurately detected with this device.

There are several kinds of testers in which the very common ones are portable one. They come in 50, 100, 250, 500, and 1000 volts. Of course, you must not overlook the principle of parallelism; you have to use the right tester for the right system. This means that if you are going to test an electrical system with high voltage, you have to use testers that are capable of holding such current; if you are going to test a low voltage system, you have to use low voltage testers.

Benefits of Using Uninterruptible Power Supply

The UPS or uninterruptible power supply is great tool to avoid sudden turning off of your appliances, computers and other electrical devices or equipment. It provides electrical current for your electrical device for up to five to twenty minutes. Such a fraction of time is enough to have your appliance or computer be turned off properly. For instance, if you are working with the use of a computer and then unexpected power brownout or blackout comes into place, you are given the time to save your computer works.

UPS allows the user of electrical device to be operated with safety by giving you time to safely shut those electrical devices down. Sudden turning off of the computer or any appliances can greatly cause damage or malfunctioning the next time they are used. Since UPS avoids destroying your electrical equipment or devices, it helps you save big bucks in buying another set. This is because UPS prevents power surge and power sag that would significantly ruin your computer or any equipment that consumes electricity.

There are two types of UPS namely standby UPS and continuous UPS. The difference between the two is the way that the electric current is passed through the electrical device. With standby UPS, the electrical device is supplied with the main power supply even if it passes through the equipment and the internal batteries. The power in the internal batteries is only utilized once the main power supply is down or blackouts.

With continuous UPS, the electrical device is supplied with the power through the internal batteries which is charged through the main power supply. This means that it can give power supply to the electrical device longer as long as the internal batteries never run out of electric supply.

But it really is a great test device and Hioki really did an impressive job on it—it is worth the price.

What is an Oscilloscope

One of the most useful test equipment for troubleshooting is the oscilloscope. It is very useful in the design and repair of electronic equipments. In the very distant past, before the 1980s when digital oscilloscopes came into popular use, there were just oscillograms, where the galvanometer is used to take measurements, and then the corresponding graphs are inputted as hand drawn drawings. Afterwards came the automatic paper-drawn oscillograph, which later on was developed into an oscillograph. It was in 1940s that the two geniuses, Howard Vollum and Jack Murdock designed the first triggered oscilloscope. Ever since then the technology advanced until today, where oscilloscopes may now have extra features.

The oscilloscope is utilized to analyze and describe the frequency of the oscillating electric signal and also to determine the time and voltage values of signals. That is because the oscilloscope is designed to be an electronic device that is able to show graphical illustrations on its screen and make further breakdown analysis out of these electric signals.

There are actually a vast variety of oscilloscopes. Some of them are the CRO (Cathode Ray Oscilloscope), the dual-beam, and analog type. Oscilloscopes such as spectrum analyzers are especially designed to have sensitive inputs, and can display spectra well into the GHz range. The most sophisticated type are the digital ones, and by its name you can tell that it does its reading digitally. Under the digital types there are more innovations such as the digital storage oscilloscopes which are preferred more in industrial applications.

Oscilloscopes can be used for scientific researches and technical investigations, and even for medical purposes. It can also be used by some repair technicians.

This instrument is not all beauty and extra decorations. Investing into such a device can mean significant capital savings and even a boost to your productivity with its time efficiency, precision and convenience.

Keep your Industrial Business Safe Test Equipments

Most of us entwine our lives with the comfort and ease brought about by modern gadgets, and industrial and manufacturing business have also taken advantage of the efficiency of the modern machineries and facilities. On the other hand, technicians and inventors have also created items that could blunt the negative side of the two-edged sword of technology. They have come up with the creation of test equipments that reduces the possibility of tragic accidents caused by innocent usage of malfunctioning machineries or defective devices.

There are three ways to acquire these test equipments for your own use: Option 1, purchase brand new equipments; Option 2, buy them secondhand or used on; or Option 3, just rent them from a credible rental company. The latter option is slowly becoming more and more popular choice, obviously because it cost lower, and also because of some extra perks in the rental deals such as having free technical support. However, there are still a lot who would want to have their test equipments for keeps.

Between Options 1 and 2, the second one is still the preferred one. Many people would find their budgets short to buy brand new equipments, which is not very surprising actually, considering how expensive these things can get. In today’s time people consider buying used equipments the more practical choice. This is why lot of test equipment businesses are now also selling or auctioning used test equipments, even though their original business is selling the brand new ones. There are also some companies that provide all three options to their customers.

The important thing actually is not the acquisition of test equipments itself. It’s actually conducting test on your machineries and equipments to guarantee your business’ safety against possible industrial accidents.

Four Pointers on Buying Secondhand Test Equipments

Test equipments are vital for the maintenance of a productive and highly efficient machineries and gears, and businessmen know this. To acquire the appropriate equipments the head of a manufacturing company may choose over buying a brand new one, or to purchase second-hand equipment.

Most companies would prefer the second one over the first option, simply because it gives more opportunity for the budget. The only risk to be avoided in shopping for secondhand equipments is purchasing defective equipments and those which their life spans are considerably shortened. Acquiring equipments that are way past its best, or those which are decent, but not for very long would be equivalent to being “ripped off”. So here are a few pointers to guide you when shopping for test equipments (some tips would apply to buying secondhand gadgets too).

1. Decide on what you really need, and even what you want. This means determining what test equipment your machines actually need, and would also include deciding whether to get the latest or the more complicated and sophisticated version available (still secondhand, obviously), or to stay with the simpler, less complex ones.

2. Check out a lot of companies selling secondhand test equipments (you can shop online to save time, effort and gas). See if they have what you want, and check out their reputation as secondhand test equipments provider. No, it doesn’t entail hiring a detective or something, just checking the feedbacks from past customers would do the trick. You may also listen to recommendations made by people you know. See if they have the instruments you need.

3. Proceed to comparing prices. The reason you are buying secondhand equipments is clearly so that you can make the most of your funds. This strategy helps you find which company provides the best deal.

4. When considering the prices, also take into account the services they provide. Between the choices of a company who will give you the equipment and a short-time warranty for a certain price, and another company that provides free technical support and a longer warranty at a slightly higher price, you might want to choose the second one to get a better deal. But if you are not concerned so much with the warranty and the free service than the price, then you can go with the first choice.

Getting secondhand test equipments is not that bad if you get a good deal out of the limited fund you have. But if you want to optimize your opportunities with your capital, another option you can take is to try test equipment rental. A lot of gears are now available for rent, and some companies such as TechRentals are even providing the latest technologies, at very reasonable rental costs.

The Importance of PAT Testing

True, we have depended much on our electrical and electronic machineries and gadgets as we live our life. Everywhere we go it would seem almost impossible to live without such items, unless we go camping (even then, we can’t even go without electrical things like flashlights). In our normal daily routines we go through the day making use of complicated devices. While electrical appliances do eases our daily burdens, these can also pose a huge threat to us if we are not very careful. A lot of accidents have happened in workplaces because of damaged and defective electrical or electronic gears, which could have been prevented if certain standards are specified for such equipments.

This is why there is now the existence of certain legislations designed to protect the employers’ safety against electrical mishaps. One of them is the PAT testing of electrical appliances and devices which checks whether the said equipments comply with the health and safety standards imposed.

To ensure the safety of your establishment, you can either hire the services of professional PAT tester provider or train your own staff to do the test for you. If you are concerned with the financing of the PAT testing, PAT tester rental could be a good option. If you choose to rent, try to find a rental company who can provide expert technical assistance for you. PAT testing should be regularly conducted, either in 3-months or 6-months basis, depending on the risk that the devices entail.

“Better safe than sorry” should always be one of the standing principles in workplaces. Electronic appliances and electrical equipments are friends if they are safe to use and if used appropriately. If not, they can not only put your investments to ruin, but also be a threat to many lives. Although PAT testing would cost you, the money you invest in it could save you from the disaster that would cost much more if you neglect doing it.

Why You Should Rent Computer Equipments Instead of Purchasing Them

In the present times, when you are into the business, it is important to take capital consideration of the technological assets you must have, especially computer equipments. While some would prefer to buy either brand new or used items of this sort, it could be a good choice for a starting company to rent so as to be able to resourcefully spend its capital. In leasing the needed computer equipments, the company would be able to start up straight away, and would probably have extra funds for unexpected expenses instead of having to spend everything for equipment purchases.

True, rentals are temporary means for acquiring an equipment. This is the reason why it is advantageous for start-up businesses, and can also be agreeable to established businesses. Since rented devices only last in your hands until the contract expires, there is an open opportunity to upgrade yourself by choosing the more modern and advanced ones after returning the items leased. And for those who do not wish to do that because they prefer to operate with what they were already used to, a lot of rental companies allow negotiations on extending the rental contracts. Having these options is quite convenient to both the business newbie and the pro.

It is also a plus factor that rental companies provide technical support for their clients. Companies who do not prefer to hire full time IT staff or just do not have the financial capacity to do so would find that rental of computer devices suit them very well. Not only does the rental company shoulder the updates needed, the renter also have to worry less on the cost of repairs.

Buying computer equipments is a mark of permanence. Yes that is a good sign, but in the present era where progress means continuous advancement and technological sophistication it might be better to choose something that could match the rapid pace of development we are experiencing. Renting your computer equipments needs is a just the thing that can make you walk, no, run with such ever-speeding tempo.

Spectrum Analyzers Rental

The world is full of complex things, and some of these elements we one can’t see with our naked eyes. However, humans have continually explored the endless possibilities and tried to know the unknown to benefit the race of mankind. We are, in fact trying to match the complexities we find with the gadgets we use, and with such items we see what used to be unseen and unperceivable, such as the light waves and sound waves.

Spectrum analyzers are testing instruments used to check the spectral composition of the different frequencies of some specific waves traveling through air. With this gear, the electric, optical and acoustic waves and their frequencies, which usually cannot be seen, can be viewed graphically. There are also some analyzers that present the data in statistical manner.

There are people who need spectrum analyzers vary from engineers and technicians to scientists and experts wanting to have a good study on these waves and maybe put them into action for their creations and inventions, or attune them up. Many great and useful devices we use that depends upon these waves such as the telephone, radio, televisions, and a lot more. There are varying spectrum analyzers that are used depending on the frequency ranges and the waves to be studied. Spectrum analyzers are created intricately designed to study specific waves.

The complexities of these devices are also matched by the prices they have. Spectrum analyzers can be very costly, but thankfully there is a cheaper alternative to buying one. Some companies now provides rental for these equipments, which is a good choice for a lot of those who needed these equipments for only a short period. Also, for people who might be lacking the technical skills or the know-hows of these equipments would be well-advised to acquire such complicated contraptions from rental companies who also provide technical support, and much better if it is for free.

Going for rental services is getting to be a popular option for a lot of people nowadays, which may be attributed to the recent economic setback we have experienced. It is really great that we can now have a lot of devices by just renting them, even equipments as complex as spectrum analyzers.

3 Tips on Computer Rental

Computers have indeed changed the lives of every human being in everything they ought to do. It has entirely changed the world even from the simplest details to the most complicated ones. It has sped up tasks which usually take an hour but now it merely takes only seconds to finish, and perform them more easily, accurately and swiftly. These are the many wonders brought about with the coming of the computer era.

Come to think of it, we are indeed a civilization run by technology. However, the prices of these amazing technological contraptions can be very expensive. This is why resorting to computer rental companies is quickly becoming a fast trend among people, corporations, industries and even educational organizations. Aside from the advantage of being able to acquire computers at a much lower rate, computer rental services are also popular because of a lot of businesses needing computers for temporary period. This course of action has now become the trend in the realm of commerce.

With these and many other advantages that computer rental provides, I won’t be wondering if you would also want to follow suit. If you do so, please take the following tips into consideration prior to renting computers.

Shop around. Find out which companies offer computer rental services, more preferably on the internet so that you can check on the background and credibility of these companies. Find out if they are legally credible and reliable. This diminishes the risk that you could become a victim of fraud or being counterfeited.

Check the location. This is because it would give you a general idea on how much money you would have to pay for the delivery expenses. Delivering to a business address is more convenient than delivering the computers on certain conventions because the former has more close-in parking areas, installation rooms, and is less time consuming as compared to the latter.

Mark your computer specifications. Obviously, if you want a more advanced operating system or software to be installed, your computer rental rates will also increase. Fairly so, one of the best reasons why it is very advantageous to rent computers because you get to use far more better equipments than you can probably afford to buy.

Computer rental is a practical strategy to get the computer you wanted for a much lesser price. The trend continues to spread and although it is available only to some countries, we could expect that the future holds a much wider market for it.

Automated Test Equipments

The birth of gadgets and technological devices has relieved us from the ultimately hard labors that the people of our distant past had to endure. True, the literal meaning of the statement “sweat and blood builds the most amazing fortresses” is applicable to the creation of some of the most famous landmarks we see today such as the Pyramids of Egypt, but with the help of our advancement in technology we had discovered how to create things that would have been impossible in the past centuries. We wouldn’t have the easy comforts of using appliances and other machines

Yes, we live what we can consider a “good life” because of the electric gadgets. And to assure that these gadgets would actually work and to avoid accidents that can be encountered when dealing with electric materials it is no longer a trend to rely on luck, but we assure ourselves by checking their reliability with appropriate test equipments. The most common devices used for PAT (Portable Appliance Testing) are backplane testers, battery testers, burn-in test equipments and automated ones.

Although it is probably the most costly of all of these testers, the automated test equipment is the most sophisticated, and probably the most labor-efficient especially when there is a need to mass-produce industrial units, considering that it requires the least manpower. With automated test equipment, computers are used to program the device so that it would be able to check and measure apparatuses such as printed circuit boards, integrated circuits and other related contraptions. Automated test equipment can be very complex machineries such as a flying-probe tester, although there are also simple ones, such as the digital multi-meter.

With the expensive cost of automated testing equipments, it might be impractical for starters to purchase one. However, there are rental companies who provide not only the equipment but also the technical support needed for it. Renting the devices needed is an emerging trend today, and this proves to be good investment for business of all sizes too. Aside from the cost you cut from the budget for the purchase of the item you need, it also conveniently saves you from collecting technologically obsolete mechanisms.

Human Factors against the Effectiveness of Leak Detection Methods

Environmental factors such as wind or breeze and ambient light, affects the effectiveness of leak detection process. Additional information is that ambient sound also plays a role in the ineffectiveness of the workability of detection methods applied.

Ambient sound obviously would affect the accuracy of result when you use ultrasonic detectors. This type of detector is not ideal for noisy environment or a type of refrigeration system such as parallel rack. The pressure-regulating valve also produces the same noise that leaks make.

Another factor to deal with is the human factors. If you are an experienced technician in leak detection process and able to master it, it is still not an enough ground to have successful leak detection. Using and maintaining your leak detection devices are two most important tasks you should keep in mind.

Although most detectors are easy to use such as bubble solution methods, you also need to upgrade you knowledge about it. With the advent of newer technology, even in bubble solution method, there are other ways of performing it better and more advanced.

Replacing the parts of your detection devices and cleaning it after use should not be overlooked. Once you have not performed any of the mentioned things, there are big chances of arriving at false results because of faulty working detector you are using.

Electronic Sound Detection Method: The Good and Bad Aspect

Ultrasonic sound detection method depends on a high-frequency sound created because of the movement of gas from one pressure to another; the orifice where the gas escapes normally produces 40 KHz and higher.

Try to imagine how humans create sound or voice; the air that escapes or pass through the vocal box, which is a hole enables the humans to produce sounds by letting the air pushes through that hole (vocal box). This phenomenon is similar to having leaks in refrigerants. With electronic sound detector, the leak can be pinpointed or determined.

The greater the pressure inside the gas container or refrigerants, the greater noise there would be because the gas pressure is directly proportional to the turbulence created. The noise is almost inaudible to human ears, much like the whistle of a dog which is at a very high frequency. Hence the detector is named “ultrasonic.” With their highly sensitive microphones, ultrasonic sound detectors are the only ones that can hear such almost inaudible sound.

The same situation also happens in vacuum; the vessel or evacuated system is where the gas rushes into, creating a high frequency sound. However, the only difference is that the noise or sound is generated inside the system, not like in a refrigerant or a gas container in which the noise is generated outside the system.

Methods of Leak Detection for Refrigerants

Having a leaky system that would lose your refrigerant is a very usual service call. Locating the source of the leak is not easy even if it may be easy to diagnose such problem.

You need to hire a technician in order to find problems on refrigerant leaks. The technician expert on leak problems has all the knowledge in using several methods of finding the leaks. However, there are both advantages and disadvantages in several methods known applicable. Some methods are effective but not as good as the other.

The reason why there should be several methods to be used in detecting leaks so that if one method is not working, then other methods may work well. The usual method is to locate suspected area and to pinpoint the very exact leaking area of a refrigerant.

Here are the methods of detecting refrigerant leaks.

(a) Soap Bubbles: This is the easiest way of detecting leaks by using an approved soapy solution. The suspected area is saturated with soapy solution. The solution will bubble if a leak is present. If the system is well-pressurized, this method works fine. You can also use other methods as verification process of detection.

(b) Visual Inspection: This is for locating only the general area of suspected leaks. The refrigerant leaks often come with the leaks in refrigerant oil. However, this may not always be true in some cases.
The leak location is usually surrounded with stains from refrigerant oil. Signs of oil in your refrigerant are the very common factor of leaks.

Benefits of POS Barcode Scanners

Spending too much time in waiting is painful. If you have retail business and this is the situation that is going on in your retails store, the more likely that you will lose some of your customers. Speeding up the buying process such as computing the items to be bought would bring your business to the next level. In order for that to achieve, you need POS barcode scanners of the items or products that you are selling.

The products are scanned through the barcode scanner so that the pricing, the product category, product code, and other aspects are immediately recorded and stored in the POS computer. You won’t be doing the ancient old type of running the retail business, in which you have to do everything manually. With POS bar code scanner, the process is very fast, helping you save time or to have time in doing other important things regarding your business. Although, the difficult process here is that you need to tag every item in your store so that they can easily be read through the barcode scanner. It will take time, however, when gets done, everything will be fine and fast.

Most of the barcode scanners use CCD-based technology. Such technology is widely used by several stores, both big and small. This works by pressing the scanner on the barcode so that the information is feed to the computer. However, if most of your products are rounded, you need to have laser-based scanners because CCD-based technology is not capable of reading barcodes embedded on rounded surfaces.

Save Effort and Time with Counting Scales

It is tiring and almost impossible to attain accuracy with just by counting the parts or pieces with your hand. With the advent of measuring device like weighing scales, there have been no tiresome jobs like counting the pieces or parts one by one. The luxury of having counting scales that perform the measuring jobs for you need not be expensive. There are several types of weighing scales to choose from, depending on what suits your needs.

There is wide selection of counting scales available in the market today. They vary in sizes and shapes. Some are just enough to fit on a desk or table. Normally, counting scales have three displays that tell three measurement aspects of the object being weighed; one tells the overall weight, the second tells piece weight, and the other tells the quantity counted.

Usually, counting scales have the facility that tells the scale how heavy every item being weighed is. For instance, there are ten items on the scale, and then the process is followed by a key press that would tell you that there are actually ten items present. The scale would then compute itself on how much each individual item weighs and do the process of counting. In the end, you are given accurate counting result. However, the counting scale is more efficient in giving accurate result when the sample quantity being weighed is higher.

Have Thermal Printers for Better Business

Thermal printer is ideal for simple printing tasks such as printing receipts. Since it produces documents or image by selectively heating the coated thermal paper, it is economical than any other kinds of printers. The thermal print head is impressed onto the thermal paper once this paper passes through it, allowing texts or images to be produced.

There are thermal printers that could produce different color; the very common ones are red and blue, aside from black.

The thermal printer has components that include platen, spring, thermal head, and controller boards. The platen is the one the feeds paper through its rubber roller. The spring is the one that applies pressure to the thermal head; it is a device that causes the thermal print head to contact the thermo sensitive paper. Lastly, the controller boards are used as a mechanism for controlling.

There are three kinds of thermal printer—thermal wax transfer printer, wireless thermal printer, and direct thermal printer. Thermal wax transfer printer presses the wax coated ribbon onto the paper with the use of heat so that the image or text is transferred. When the ink cools on the paper, it becomes permanent. What’s good with this is that it can print colorful images or texts. Wireless thermal printer uses Bluetooth technology or infrared beams so that the data is connected to the computer, allowing the document or images to be printed. Direct thermal printer is the most common one because it is ideal for printing receipts and a lot of business establishments use this. It works with the use of burning dots being contacted onto the coated paper so that images or texts are created.

What are Data Loggers?

Data logging factors are what make meteorologists being able to assess local weather forecast. Water depths, flow, and levels are measured through data loggers. Perhaps, you may be wondering how on earth does traffic reporters are able to determine how many people have travelled in a certain highway for a particular period of time; data loggers is what makes this possible. Manual counting of vehicles that pass through the road is really impossible. Road traffic counting is basically done through data logging factors. These are just few of many things that data loggers can do.

There are several kinds of data loggers today. The kind of which should be used merely depends on the job. For more extensive research, larger machines are needed while small jobs would use simple or smaller data logger machines. Data logger is defined as computerized electronic device that document certain data for a specific predetermined span of time.

The data loggers are responsible in providing time and date indicator to make the breaking down of recorded data easier to do. This is due to the fact that it is accurate by recording detailed information. Informational researchers use this system to make the analysis not only better but more importantly, accurate.

There are several kinds of data loggers available in the market today, from simple to complex unit. There is a wide range of flexibility so that data retrieval tasks are easily accomplished.

Kinds of Digital Scales (Part 1)

Digital scales equipment are widely used and thus very in demand in various industries worldwide. Analog weighing scales are rapidly replaced by digital forms, although there are still some who prefer analog designs. There are several digital scales offered in the market today. The categorization of digital scales is mainly based on their usage.

Common digital scales types include diet, bathroom, counting scales, baby, adult, animal, laboratory, crane and truck, food, nutrition, metal weighing, and shipping and postage. Hospitals, pediatric clinics or doctor’s offices usually have baby and adult scales. Such types of scales are important for regular checking of the client health.

Nutrition, food and diet scales are the ones used in determining the amount of food intake by the individuals who want to achieve better health condition. That is why body builders and those who are aiming of losing or gaining weight have this kind of scales. Bathroom scales are generally used by any individuals who simply wish to know how much they weigh. Body fat measurements equipment are also common added features to some of these scaling types.

In medical and scientific fields, laboratory scales the very common ones seen. Such type of scales measures tiny particles accurately such as lint and dust particles.

Kinds of Digital Scales (Part 2)

In agriculture areas, animal scales, of course, are the ones being used. They are utilized to weigh the weight of animal farms such as cows, chicken, swine and many others. Truck scales are used purposely for way heavier things to be weighed such as vehicles. Tankers are even weight with such scaling type. Crane scales, on the other hand, also lift heavy materials. They have lifts to take heavy objects and measure their weight.

Metal weighing scales are very common among pawnshops and other metal or jewelry manufacturers. This type of scales weighs silver, gold, and other valued metals used for aesthetic purposes. Metal weighing scales are important among jewelry stores to give accurate prices whether for buying or selling such things.

Postage mails and parcels are weighed through postal scales. New generation digital postal scales are a bit easier to use because you can program them with postal rate information. This is a big help because it displays the right amount for postal services every time the value changes in the market.

Of all these scaling types, counting scales are the very common ones. These are used for counting coins and currencies. In some industries, they use counting scales not only to take weights but also to count parts as well.

Test and Measurement

As we live in the electronic age, our technology is advancing in leaps and bounds. Robots are now being developed to help clean the house. Bipedal or walking robots are now being exhibited in tech shows that happen all around the world. If it wasn’t for the latest test and measurement equipment, inventors would have difficulty in producing their work.

With the aid of computers, we are now able to design machinery that is much more complex. We can now build structures that were once thought impossible. The invention of such a machine now makes our lives a lot easier. With the latest data and telecommunications equipment, ideas can now be shared by people all over the world.

Utilizing the latest equipment, we even now have the ability to go into space. It wouldn’t be long when we could visit other planets in our solar system. This would not be at all possible without the help of test and measurement equipment. The most advanced computers can now simulate almost anything. From car crashes to landing on other planets, this is how far we have come. We can now predict how an object would react to certain situations even before the actual production begins.

All things new come with certain complications. Murphy’s Law states that “Anything that can go wrong will go wrong”. As much as possible, knowing what can go wrong in advance is a lot of help. Plans can be put into place to avoid such problems. This is certainly true for automobiles and aircraft.

This is where the importance of test and measurement equipment comes in. Without these items, fabricating things just got a lot more difficult. The vehicles that we ride in everyday are made safe because of these items. And without them, we would be back in the stone age.

What You Need to Know about Current Transformers

Current transformers are electrical device that aids in protecting your appliances at home or office. They provide flow of current in secondary circuit that is directly proportional to the amount of current in principal circuit. Current transformers are used to monitor the operation of power grid and calculate the current.

Electrical power industry utilizes current transformers for protective and metering purposes. The transformers manage the flowing of current especially if it comes from a high voltage-producing source. The well-insulated toroidal core being wrapped with windings of massive wires serve as the controlling passage of the electrical current, avoiding circuit overload. The power being used by a certain establishment is monitored because with this kind of transformer, you can have a view of how much current is flowing.

The physical configuration of current transformer, rating factor, and many others are factors that improve the accuracy of current transformer’s measurement and workability.

Ambient temperature is the basis of CT rating factor. The rating factor is used to identify the appropriate primary current measurable at maximum level. It regulates the current by multiplying the fill load. The current transformer would have low capacity in order to retain the level of precision in terms of measurement. The temperature of CT should have ranged from 35-55 degree Celsius.

Vibration Analyzer

Vibration testing is necessary in determining whether the machine is in good working condition or already suffering from minor to major mechanical flaws. In most cases, even the newly created machines are also tested in the laboratory if it will survive operating for a certain defined time span.

There are many factors that need to consider. The commonly utilized things include climatic chambers, data analyzers, vibration meter, controllers, accelerometers, level recorder, displacement transducers, vibration exciters, and many other test gears for mechanical vibration.

Other vibration test equipment that is also important in vibration analysis is called transducers. They convert mechanical energy into electrical energy. Through the electrical signal being produced, the functionality is defined.

Accelerometers are the commonly used transducers because of its outstanding sensitivity and wide spectrum of frequency. This test equipment usually comes in small size and weigh lighter than any other kind of transducers. They do not need the loading of vibrating mechanism just to get the rest results because it would calculate the vibration at a certain point.

Just like any other mechanical, chemical, physical, industrial, or general test equipment, vibration test equipment also very from simple to complex. Some devices only give binary results such as pass-fail results while other give sophisticated data of analysis. Most of vibration test equipment provides graphical display of data results for easier comprehension during analysis process.

Kinds of Pat Testing Equipment (Part 1)

Fires at workplace commonly happen due to the neglect of simple task such as equipment maintenance on electrical machines, appliances, and many others. Regular testing of such equipment is a requirement to avoid life-wrecking incidents such as fires.

To prevent such bad things to happen in any establishment, pat testing should be performed. There are lots of pat testing tools to choose from; of course, it is best to choose the one that suits for your company or establishment.

Two kinds of pat testing include simple pass or fail pat testing and manual pass or fail pat testing equipment.

(a) Simple Pass-Fail Pat Testing Equipment

This equipment is used for most basic testing system. When this is used, it is only displayed on the indicator if the appliance being test has passed or failed according to the standard safety. This kind of equipment is best for small units or unsophisticated appliances. The disadvantage part is that this does not work on complex equipment. It does not provide detailed information on the test result, too. Its capacity is limited only on insulation resistance and earth continuity aspects of test.

There are some instances that this equipment encounters false negative result. This leads to giving a failed result even if the equipment is in excellent working condition.

Kinds of Pat Testing Equipment (Part 2)

(b) Manual Pass-Fail Pat Testing Equipment

This is a little bit more advanced than the abovementioned system. This offers greater functionality because of its ultimate performance on pass/fail test result. It has added features that include details on how to fix the problem. However, this only works best for experienced users on manual testing processes. Proper training is important in order to do the manual testing appropriately.

Finding the right equipment for you is a skill that should be learned by a customer. The purchasing process is not as simple as buying items at grocery store; you need to undergo decision-making and brainstorm about which test equipment would be the best solution for your needs. Of course, the type of test equipment that you need to have greatly depends on what electrical devices you are going to test for faulty aspects.

There are also other options to have the mentioned test gears. You can either purchase a brand new item or rent. Purchasing as an option is ideal if you are going to use it regularly for an indefinite length of time. Of course, if you have enough money for this, buying is for you. However, if your budget is not enough, availing rental service on test equipment is an ideal option for you. With the offered flexible time of rental, you can choose how long you are going to use the test gear.

Visit TechRentals for more information about the appropriate test equipment for your needs. You can inquire about the products for rent, hire, or lease.

Renting Electronic Test Equipment

It is difficult to buy equipment for a single use only. The costs are too much for the worth of the item. A solution to this dilemma is by renting that particular apparatus. Renting electronic test equipment not only saves money, it assures you that you get your money’s worth. This is simply because there are suppliers out there that rent out your wanted equipment for a single day or more. It all depends on the number of days that you put in the agreement sheet.

There are a couple of advantages in renting electronic test equipment. For one, companies that do not have the resources to move equipment from their main base of operations can rent the equipment from the nearest place available. This solves a lot of logistical problems because it might cost more money to move that equipment out into the field than renting it out from a nearby supplier.

Another advantage of renting such items is the amount of money that is saved when compared to buying the same equipment. For operations that lasts only a couple of days or weeks, it is the might be the best solution. Not only can you be assured that the item works, if it breaks down in the middle of the program, it can easily be replaced.

An example of electronic test equipment that you can rent is the portable appliance tester. However, if you are going to use this equipment for a prolonged period of time, it might be advisable if you just purchase it from the electronic store. As this not only guarantees the ownership of the item, it may also come cheaper in the long run.
