Brief Introduction:

eRock-45T digital touch screen Superficial Rockwell hardness tester has high level automation, stable and reliable performance, it is equipped with sophisticated sensors so that can test data more accurate ; Large touch screen provide comprehensive data for quality control. 


Features:

1. The color touch screen will display hardness value, conversion value, test force, dwell time, indenter info. etc directly, indicator responses sensitively, show the hardness value accurately, the test value is more accurate than national standard;

2. Automatic loading - dwell - unloading test force, easy operate

3. Support English & Chinese language, menu structure

4. Built-in printer can print test result directly

5. 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;

6. The screw rod adopts the fine grinding process, which ensures that the machine can be lifted smoothly and without eccentricity, make test accuracy more higher and stable. 


Main application:

Suitable for surface quenched steel, surface heat treating and chemical treating materials, copper alloy, aluminum alloy, sheet, zinc layers, chrome layers, tin layers, bearing steel and cold and hard casting etc.
