KH-160
KH-160Series Leeb Hardness Tester-Specification
Working Principle
To use the impact body of certain weight impacts against the testing surface under certain spring force, leeb hardness means the ratio of the impacting velocity(Va) and the rebounding velocity(Vb) of the impact body when the spherically test tip is located 1 mm above the testing surface. The leeb hardness values are calculated by the following formula:
