HRD-45 Dial gauge Motor-driven Superficial Rockwell hardness tester
Determine the Rockwell hardness of ferrous metals, non-ferrous metals, and non-metallic materials; wide range of applications, suitable for quenching
Rockwell hardness measurement for heat treatment such as quenching and tempering; curved surface measurement is stable and reliable.



Friction-free spindle ensures test force accuracy;
The loading and unloading test force is completed electrically without human operating error;
Independent suspended weights and core spindle system make the hardness value more accurate and stable;
The dial can directly read the HRA, HRB and HRC scales;
