More testing instruments are available for all kinds of industries than one can even fathom, if one is willing to explore. However, what usually happens is, everywhere, the same handful of tools and instruments are put in use in a particular sector because those are the ‘trendy’ ones. Needless to say, there also exist a bunch of testing instruments which are more helpful than they’re given credit for- the underrated testing instruments.


Electrical Industry


To begin with, the simplest of elements- LEDs can be used as effective testing devices for digital circuits in the electrical industry. They give better performance than the devices which are currently in use for the same work, like voltmeters and logic probes. This, because LEDs can instantly and simultaneously show results for multiple signals, which cannot be achieved with the help of probes or a single voltmeter. Apart from this, LEDs can also be used to detect whether the circuits have been connected and powered properly, which can make the tedious process of faultfinding extremely easy. They can also be used to detect short circuits in a system. Thus, LEDs might as well be the cheapest, handiest and the most compact testing instrument, if only they were used to their maximum potential.

EMC Test Equipment

A device that tests the electromagnetic compatibility between multiple wireless devices in order to conduct smooth transmission and reception between them. Most of the times this test is ignored, and hence the equipment is not put to use as frequently as it should. This can lead to major problems in signal transmissions.

Fuel Industry

Compatibility Testers

A compatibility tester is a device which is used in fuel industries in order to check the compatibility between two liquids whenever faced with the necessity to blend a fuel with oil or fuel with fuel itself. If used, this device can help prevent sludge deposits and residues. It can also prevent the engine from improper combustion damage. It helps in indicating the need of stability additives to the fuel and also helps maintain its stability itself. Thus, with all these benefits, one must think that this instrument must be widely used, but it in fact, is again one of the underrated testing instruments.

Metal Industry

Crimping Tools

Most work in metal industries will require cutting and joining of metals. In the wake of machines used to conduct this process, the smaller crimping tools have been sidelined. A crimping tool is a handy device used for joining two metal pieces by deforming one or both of them. Apart from metals, this tool can also be used to connect devices with cables. In wire designing, the process of crimping is crucial, and is undertaken by these tools. Thus, even with a simple design and compact structures, crimping tool becomes a highly useful device.

More frequent use of these tools would not only lead to lesser errors, but, as seen in many cases, can also aid to cost-cutting as well as bringing compactness in devices. Moreover, they also help in easy usage as compared to their bulky and heavy counterparts. It is thus apparent that using these tools will only bring betterment to their respective industries.
