TH134 Leeb hardness testerDetailed product description：

TH134 Leeb hardness tester is a new type of pocket sized integrated 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 Leeb hardness, and the Leeb (HL) hardness value is automatically converted into Brinell, Rockwell, Vickers, Shore and other hardness values through the program. It can also be equipped with various testing accessories 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 parts and non removable components.

Functional features:
The TH134 integrated Leeb hardness tester is an advanced pocket sized hardness testing instrument that is easy to carry;  
TH134 is equipped with a DL type impact device;  
Directly test large and heavy test specimens or installed permanent assembly components;  
TH132 is more suitable for hardness measurement of parts such as deep groove bottoms or profiles (such as tooth surfaces);  
Can test six hardness systems (HV, HRC, HRB, HB, HV, HS);  
Can be connected to an external printer to print test results
