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 ...
