Electric Rockwell hardness tester
Model ：HR-150DT
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.
