Product name: HR - 150A Hardness Tester

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.

Feature & Use:

• Manual testing process, no need for electric controlling
•  It's steady and reliable for testing of curved surface
• Precision conforms to the Standards of GB/T 230.2, ISO 6508-2 and ASTM E18
• It's suitable to  determine the Rockwell hardness of ferrous, non-ferrous metals and non-metal materials.
• It can be widely applied in the Rockwell hardness testing for heat treatment materials, such as quenching, hardening and tempering, etc.
