Description

manual superficial rockwell hardness tester apply to test the hardness of thin parts or material surface. It has stable and reliable performance , it is economical 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

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