LK120 Leeb hardness tester

Advantages

l        Wide measuring range. Based on the principle of Leeb hardness testing theory. It can measure the Leeb hardness of all metallic materials.

l        Large screen(128*64 dot matrix LCD), showing all functions and parameters.

l        Test at any angle, even upside down.

l        Direct display of hardness scales HRB, HRC, HV, HB, HS, HL.

l        Seven impact devices are available for special application. Automatically identify the type of impact devices.

l        Large capacity memory could store 500 groups (Relative to average times32-1) information including single measured value, mean value, testing date, impact direction, impact times, material and hardness scale etc.

l        Upper and lower limit can be preset. It will alarm automatically when the result value exceeding the limit.

l        Battery information indicates the rest capacity of the battery and the charge status.

l        User calibration function.

l        Software to connect with PC via USB port.

l        With EL background light.

l        Thermal printer integrated, convenient for in field printing.

l        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).

l        Auto power off to save energy.

l        Outline dimensions:212mm*80mm*32mm. 2 Main Application &Testing Range
