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
