HARDNESS TESTER

HARDNESS TESTER

Electric Rockwell hardness tester

Electric Rockwell hardness tester has stable and reliable performance, can effectively avoid the error by manual, it is a economical Rockwell machine.

Main function and features 

1. Test force load, dwell, and unload is automatic, it is avoid the error by manual; high test precision ; good repeatability ;

2. The dial reads the hardness value directly, indicator responses sensitively, show the hardness value accurately, the test value is more accurate than national standard;

3. One-time casted molding shell, stable structure and it is not easy to be out of shape. It can work under harsh environment; the shell coating adopted car paint technology with white color. it has strong scratch resistance capability and still look bright as new after use many years;

4. Factory directly supply, we have products develop &design & produce ability, all the parts provide life-time replacement and maintenance service; 

 

Main application:

Hardened steel, quenched and tempered steel, annealing steel, bearing steel, strip steel, hardened steel sheet, hard alloy, etc.;
