Main features:

1.There are three kinds of test methods: Brinell, Rockwell and Vickers.

2. With a unique closed-loop control system, automatic loading, high precision load cell sensor. Easy install and operate, test result more accuracy. 

3. Digital Eyepiece with built-in digital encoder, measure D1, D2 value, just click button on eyepiece, hardness value and D1, D2 value etc will directly display on touch screen.

4. The test force is automatically corrected, each force is automatically compensated, and the accuracy of the force is improved by an order of magnitude.

5. Can be calibrated according to the standard hardness block or length scale.

6. Test force can be automatically corrected by standard dynamometer

7. The hardness value of Rockwell and Vickers can be converted.

8.Touch screen, menu structure, easy to operate.

9. According to the national standard /ASTM hardness automatic conversion.

10. Set password protection setting parameters, more sample and test information.

11. The measurement data U disk is saved in EXCEL format for easy editing and processing.

12. You can choose to upgrade and add two rulers, HVT and HBT.
