TH140 Leeb Hardness Tester Product Introduction:

The Leeb hardness tester TH140 is a new type of portable hardness testing instrument, mainly suitable for testing the hardness of metal materials. It has the characteristics of high testing accuracy, small size, easy operation, convenient portability, and wide measurement range. It is based on the Leeb hardness principle, and the Leeb (HL) hardness value is automatically converted into Brinell, Rockwell, Vickers, Shore and other hardness values through the program. Various testing accessories can also be configured to meet various testing conditions and environments. It is mainly suitable for rapid hardness testing of metal materials, especially for on-site hardness testing of large components and non removable parts.
