Manual superficial Rockwell hardness tester apply to test the hardness of thin parts or material surface. It has stable and reliable performance, it is economic Rockwell machine without electric power supply.
Main function and features:
1. The dial reads the hardness value directly, indicator responses sensitively, show the hardness value accurately, the test value is more accurate than national standard;
2. 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;
3. Factory directly supply, we have products develop &design & produce ability, all the parts
provide life-time replacement and maintenance service;
Main application:
Galvanized, chrome plating, tin plating, heat treatment of materials and chemical surface treatment of all kinds of thin metallic materials;
