LK120 Leeb hardness tester
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
Main Application
l Die cavity of molds
l Bearings and other parts
l Failure analysis of pressure vessel, steam generator and other equipment
