Portable Leeb Hardness Tester MH320
ADVANTAGES
1. Small volume with light weight, it is convenient for taking. Its outline dimensions are 212mm×80mm×32mm.
2. Large screen(128×64 dot matrix LCD), showing all functions and parameters.
3. Test at any angle, even upside down.
4. Wide measuring range. It can measure the hardness of all metallic materials.
5. Direct display of hardness scales HRB, HRC, HV, HB, HS, HL and three types of strength values immediately.
6. Seven impact devices are available for special application. Automatically identify the type of impact devices.
7. Large capacity memory could store 500 groups (Relative to average times32^1 ) information including single measured value, mean value, testing data, impact direction, impact times, material and hardness scale etc.
8. Upper and lower limit can be preset. It will alarm automatically when the result value exceeding the limit.
9. Battery information indicates the rest capacity of the battery and the charge status.
10. User calibration function. USB port with the PC humanity multi-functions data proceeding software.
11. Original imported high speed thermal printer support the immediate printing function. It can save data permanently.
12. NI-MH rechargeable battery as the power source. With rechargeable battery, charging for three hours, it can use for two months. Charge circuit integrated inside the instrument.
13. Continuous working period of no less than 150 hours (EL off and no printing).
14. Auto power off to save energy. Excellent after-sale service system for high quality products---two years’ guarantee and all ife maintenance.
15. Easy to buy and comfortable to use.
