Principle
This product is a Leeb hardness tester, and its Working Principle is based on the Leeb hardness testing method. The Impact body is impacted on the surface of the sample at a certain speed through the Impact device (Sensor), and the ratio of the rebound speed of the Impact body to the Impact speed at 1mm from the surface of the sample is measured. The ratio is related to the Hardness of the material. After internal calculation, it is converted into a variety of commonly used Hardness standard values and displayed.
Applications
Wide range of applications
Standards
GB/T 17394-1998
