HLN-11A Leeb hardness testerDetailed product description：

The HLN-11A Leeb hardness tester is a new type of hardness testing instrument designed based on the latest Dietmar Leeb hardness testing principle and utilizing the most advanced microprocessor technology. The HLN-11A Leeb hardness tester has the characteristics of high testing accuracy, small size, easy operation, convenient portability, and wide measurement range. It can automatically convert the measured HL value into hardness values such as Brinell, Rockwell, Vickers, Shore, etc. and print records. It can also be configured with accessories suitable for various testing scenarios. The HLN-11A Leeb hardness tester can meet various testing environments and conditions.

Functional features:
It can test six hardness systems (HV, HRC, HRB, HB, HV, HS) and can convert between them.  
Six different impact devices can be configured, （D、DC、D+15、C、DL、G）。  
Automatically identify the type of impact device (D, DC, D+15, C, DL, G).  
Few buttons, easy to operate, allowing for direct selection of testing materials and directions through the keyboard.  
The printer and the host can be separated.  
Test results can be printed.
