HLN-11A multifunctional Leeb hardness tester is used to test the Leeb hardness of ferrous metal and nonferrous metal materials.
1. Automatic digital display, without human reading errors;
2. The measured Leeb hardness value can be converted into Brinell, Rockwell, Vickers and Shore hardness;
3. The attached printer can print the testing value immediately;
4. Strong adaptability to working environment, widely used in the quality monitoring and control in production field;
6. The testing accuracy meets the standards of GB/T17394 and JB/T9378.
