MH310 Portable Hardness Tester

Advantages

1. Wide measuring range. Based on the principle of Leeb hardness testing theory. It can measure the Leeb hardness of all metallic materials.
2. Large screen LCD, showing all functions and parameters. With EL background light.
3. Seven impact devices are available for special application. Automatically identify the type of impact devices.
4. Test at any angle, even upside down.
5. Direct display of hardness scales HRB, HRC, HV, HB, HS, HL.
6. 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.
7. Battery information showing the rest capacity of the battery and the charge status. User calibration function.
8. Software to connect to PC via USB port.
9. Thermal printer integrated, convenient for in field printing.
10. NI-MH rechargeable battery as the power source. Charge circuit integrated inside the instrument. Continuous 11. working period of no less than 150 hours (EL off and no printing). Auto power off to save energy.
12. Outline dimensions;212mm×80mm×32mm
