THUS—187.5 Universal Hardness tester
Main features:
- With Brinell, Rockwell and Vickers test methods, more hardness scale selection.
- Electric loading, high precision sensor, with a unique closed-loop control system
- Eyepiece structure with digital encoder, measure D1, D2 value, LCD display hardness value and D1, D2 value directly.
- The test force is automatically corrected, each force is automatically compensated, and the accuracy of the force is improved by an order of magnitude.
- Can be calibrated according to the standard hardness block or length scale.
- Test force can be automatically corrected by standard dynamometer
- The hardness value of rockwell and vickers can be converted.
- Touch screen, easy to operate.
- According to the national standard /ASTM hardness automatic conversion.
- Set password protection for more sample and test information.
- The measurement data U disk is saved in EXCEL format for easy editing and processing.
