Feature & Use

  • The loading, holding and unloading of the test force is controlled by motor, the manual operation error is eliminated.
  • High quality integrated cast iron machine body, with the automotive paint treatment process, the appearance is smooth and beautiful.
  • Read the hardness value directly from the dial gauge, and other Rockwell scales are optional.
  • Frictionless main shaft, high test accuracy.
  • Precision conforms to GB/T230.2, ISO6508-2 and ASTM E18.

It’s a kind of semi-automatic type motor-driven Superficial Rockwell hardness tester which is specially designed to test Superficial Rockwell hardness of metal materials. It features wide application range, easy operation, good economy and practicality. It’s suitable to determine the Superficial Rockwell hardness of ferrous metals, alloy steels and hard alloys, as well as treated layers of metal surface, such as carburized layer, nitrided layer and electroplated coating, etc.
