1. Frictionless loading shaft, high precision testing force 2. After preliminary test force is applied, the handwheel will lock automatically. Automatic testing process, no human operating error 3. Precision conforms to the Standards of GB/T 230.2, ISO 6508-2 and ASTM E18 It is 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.
