Application of TT-RHA Series Manual Rockwell Hardness Tester
It is a widely used method for evaluating the hardness of various materials including ferrous metals, non-ferrous metals, and non-metallic materials due to its simplicity, speed, and versatility.

Features of TT-RHA Series Manual Rockwell Hardness Tester
- Rockwell hardness measurements for heat treatment such as quenching and tempering; curved surface measurements are stable and reliable.
- Dial gauge directly reads hardness value of HRA, HRB and HRC scales.
- Friction-free spindle ensures test force accuracy.
- Precision hydraulic buffer ensures smooth loading and unloading.
- Independent suspended weights and core spindle system make the hardness value more accurate and stable.
- Pure mechanical structure, no circuit part required, economical and practical.
