DEKKO MH-320 Hardness Tester

Overview

Advantages

1. Wide measuring range. Based on the principle of Leeb hardness testing theory. It can measure the Leeb hardness of all metallic materials.
2. Large screen (128x64 dot matrix LCD), showing all functions and parameters.
3. Test at anay angle, even upside down.
4. Direct display of hardness scales HRB, HRC, HC, HB, HS, HL.
5. Seven impact devices are available for special application. Automatically identify the type of impact devices.
6. 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.
7. Upper and lower limit can be preset. It will alarm automatically when the result value exceeding the limit.
8. Battery information indicates the test capacity of the battery and the charge status.
9. User calibration function.
10. Software to connect with PC via USB port.
11. With EL background light.
12. Themal printer integrated, convenient for in filed printing.
13. 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).
14. Auto power off to save energy.
15. Outline dimensions : 212 x 80 x 32mm

8. Rapid testing in large range and multi-measuring areas for large-scale work piece.

Testing Range

1. Testing range refer to Table 1 and Table  in the Appendix

Working Conditions

1. Working temperature : -10°C ~ +50°C
2. Storage temperature : -30°C ~ +60°C
3. Relative humidity : ≤90%
4. The surrounding environment should avoid of vibration, strong magnetic field corrosive medium and heavy dust.

Safety Instructions

1. The instrument can only work with specially designed battery pack and power adapter (charger) supplied by Mitech Co.LTD. Working with others may in result in damage bof the instrument battery leakage, fire or even explosion.
2. Do not cast the battery pack into fire and do not short circuit, disassemble or heat the battery pack, otherwise battery leakage, fire or even explosion may occur.
3. Do not open the cover of the paper compartment or come into  contact with the heating head of the printed by hand or any part of your body to avoid burns due to high temperature when the printer is printing.
