Laboratory Use Portable Ultrasonic Hardness Tester
Introduction:
There are many kinds of methods that can be used for hardness testing, and the more commonly usedmethodsare Brinell, Rockwell, Vickers, and Leeb test methods. Among them, Brinell and Rockwell test forceislarge, indentation is large, and the surface damage of the sample is large, while Vickers adopts optical methodtomeasure, which requires very professional technical personnel to operate, and can not directly test largeworkpieces; The ultrasonic hardness tester adopts the ultrasonic contact impedance method to compareandmeasure the styles, which has the advantages of high accuracy, fast speed, portability, and easy operation.
Standards:
DIN 50159-1-2008; ASTM-A1038-2005; JB/T9377-2010;JJG-654-2013; GBT34205-2017
