Universal hardness tester

Universal hardness testerHBRVD-187.5A1The model adopts a rotating test force transformation mechanism and an optical measurement system, and is equipped with a microscope measurement device on the body.

Universal hardness testerHBRVD-187.5A1The type has multiple testing forces and multiple indenters, used to determine the Brinell, Rockwell, and Vickers hardness of metal materials or specimens. Suitable for hardness measurement of ferrous metals (steel, cast iron, soft steel, quenched steel, etc.) and non-ferrous metals (aluminum alloys, copper alloys, etc.), and can also measure the hardness of hard alloys, carburizing layers, and chemical treatment layers.
