The term “Hardness” is defined as the ability of any material to resist indentation. It can be determined by measuring the depth of the area of the indentation. Hardness is not a physical property of material rather it is simply a response to a specific test. So, the tensile strength of any material can be determined by testing its hardness using various tools.
A traditional hardness tester is gigantic, bulky, and unportable. This is why materials have to be brought to the tester if the measurement has to be done urgently. But, some metals are not easily transportable. In such cases,portable hardness testers are very useful.
One such amazing innovation is the ultrasonic hardness tester. This instrument is light-weight and has a compact size. Therefore, users can bring the tester and can measure metals anywhere they want.
The ultrasonic contact impedance hardness tester or simply known as UCI hardness tester is a non-destructive tool as the measurement is done using ultrasonic vibration.
This is only one of the many advantages of this innovative device. Some more benefits of using this modern tester are as follows:-
It is also suitable for measuring the hardness and thickness of complex geometrical designs, hardened surfaces, and weld seams.
The device is portable and also has a built-in rechargeable battery to measure materials also in a situation where there is no power supply.
The instrument has an internal protection circuit to avoid interference.
The measurements are both fast and reliable.
Paraphrasing technical definitions shouldn’t come at a cost of understanding. However, this doesn’t mean portable testers are inaccurate & unable to match the benchmark standards. Over the years, the portable hardness testers have improved. Though it finds amid a controversy due to different perspectives, there’s no apparent need for undermining the efficacy of portable hardness testers. As facts would have it, the use of device probe (ball, cone, or pyramid) helps in testing the hardness and performances have comparatively increased. Each test piece differs for variables like material hardness properties, elastic properties, behavior, etc. Therefore, a proper correlation should be established with a bench-top tester. A modern ultrasonic hardness tester equips LCD, microscopic indentation, higher calibration efficiency, and lots more. Widely used for measuring the hardness of test pieces like flange edges, sheets, molds, turbine rotor, wheel, shaft hardness, etc., the ...
