Feature & Use

  • Lengthened and enlarged work table with twin-axis linkage structure, which make it very suitable for hardness testing of large and thin work pieces.
  • Direct hardness reading from dial gauge.
  • High quality integral casting cast iron machine body, with automotive paint treatment process, the appearance is smooth and beautiful.
  • The loading, holding and unloading of the test force are controlled by motor, the manual operation error is eliminated.
  • Precision conforms to the Standards of GB/T 230.2, ISO 6508-2 and ASTM E18

This lengthened Rockwell hardness tester is specially customized on the basis of normal motor-driven type Rockwell hardness tester. The structure and worktable are specially designed which make it more applicable. 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.
