Universal Hardness Tester(1)

Universal Brinell, Rockwell and Vickers Hardness Tester




1. DHU-100 Universal Brinell, Rockwell and Vickers hardness tester can measure Brinell, Rockwell, superficial Rockwell, Vickers and other hardness values;
2. The computer can control hardness testing methods, process and calculate hardness values;
3. Automatic loading and unloading;
4. When measuring Rockwell hardness, automatically apply pre-load. Maintain the hardness testing data, and it can be checked in the database;
5. Automatically generate customized inspection reports.
