The manually operated HR-150A Rockwell hardness tester is highly appreciated for its perfection and very easy operation. This machine uses the standard preliminary test force of 10 kgf. And main loads of 60/100/150 kilograms conform the international Rockwell standard. After each test the HR-150A shows the Rockwell B or Rockwell C hardness value directly on the dial indicator.

Details:
The preliminary test force has to be applied manually, followed by applying the main load by means of the lever at the right side of the hardness tester. After unloading the dial indicates the requested hardness value directly with high accuracy and repeatability.
