LK120 Leeb hardness tester
Advantagesl 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
