MH310 Portable Hardness Tester
User calibration function
Auto power off to save energy.

ADVANTAGES

• 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.

•  Seven impact devices are available for special application. Automatically identify the type of impact devices.  Test at any angle, even upside down.

•  Direct display of hardness scales HRB, HRC, 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.

•  Battery information showing the rest capacity of the battery and the charge status.

•  User calibration function.

•  Software to connect to PC via USB port.

•  Thermal printer integrated, convenient for in field printing.

•  NI-MH rechargeable battery as the power source. Charge circuit integrated inside the instrument.

• Continuous working period of no less than 150 hours (EL off and no printing).

•  Auto power off to save energy.

•  Outline dimensions:212mm×80mm×32mm
