Electric Plastic Rockwell hardness tester
Model ：XHR-150DT
Electric plastic Rockwell hardness tester apply to test the hardness has stable and reliable performance and 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 :
Pure copper, beryllium bronze, phosphor bronze, malleable cast iron, hard plastic, hard rubber, synthetic resin and friction materials
