Overview
- Compact and integrated. The impact device and the main body integrated together.
- Wide measuring range. Based on the principle of Leeb hardness testing theory. It can measure the Leeb hardness of all metallic materials.
- Large screen LCD, showing all functions and parameters. With EL background light.
- Test at any angle, even upside down.
- Direct display of hardness scales HRB, HRC, HRA, HV, HB, HS, HL.
- Large memory could store 100 groups (Relative to average times 32~1 ) information including single measured value, mean value, impact direction, impact times, material and hardness scale etc.
