Product Description
A Leeb hardness tester is a portable device used to measure the hardness of metals quickly and non-destructively. It's commonly used in various industries such as manufacturing, construction, and engineering for quality control and inspection purposes.
The principle behind Leeb hardness testing involves a small, spring-loaded impact body with a tungsten carbide tip that is propelled against the surface of the material being tested. The device measures the rebound velocity of the impact body after it strikes the surface. The rebound velocity is then converted into a hardness value, typically expressed in units such as Rockwell, Brinell, or Vickers hardness.
Leeb hardness testers are popular due to their portability, ease of use, and ability to provide quick hardness measurements without the need for extensive sample preparation. They are particularly useful for testing large or awkwardly shaped parts where traditional hardness testing methods may be impractical.
