Automatic Digital Rockwell Hardness Tester GT-HRS-150
Product Introduction
|
Rockwell hardness Tester is suitable for the hardness test for ferrous metals, nonferrous metals and non-metallic materials .
Principle: Under certain conditions, the indenter (diamond cone, ball or carbide ball) is pressed into the surface of the sample, which takes two steps. After removing the main test force, measuring the residual indentation depth h at the initial test force. The residual indentation depth h represents the level of hardness.
