Portable Hardness Testing by Leeb rebound Hardness Tester

The Leeb hardness testing method is a dynamic hardness testing procedure. Over the spring force a impact device (Carbide balls, for special applications a diamond tip) is fired onto the sample surface. The measurand is the difference between the impact and rebound speed of the impact body. The loss of the velocity is directly related to the hardness, taking account of the calibration and in accordance to influence of the mass and the surface of the sample.
