Portable Leeb hardness tester LHT310
Brief Introductions:
Introduced:
◇ Wide measuring range. Based on the principle of Leeb hardness testing theory. It can measure the Leeb hardness of all metallic materials.
◇ Large screen, showing all functions and parameters. With EL background light
◇ Test at any angle, even upside down.
◇ Direct display of hardness scales HRB, HRC, HV, HB, HS, HL
◇ Seven impact devices are available for special application. Automatically identify the type of impact devices.
◇ Large capacity memory could store 500 groups (Relative to average times 32 ~ 1 ) information including single measured value, mean value, testing date, impact direction, impact times, material and hardness scale etc.
◇ Upper and lower limit can be preset. It will alarm automatically when the result value exceeding the limit.
◇ Battery information indicates the rest capacity of the battery.
◇ Software calibration function; Software to connect with PC via USB port.
◇ Compact metal case, suitable for use under poor working conditions
◇ Continuous working period of no less than 50 hours with two alkaline batteries(AA size); Auto power off to save energy.
