Product Features & Applications
Product Feature：
- Equipped Brinell, Rockwell, Vickers test methods for more variable hardness scales.
- Closed-loop control system with high precision load cell,no need to install weights
- 8’’Touch screen, easy to operate
- Eyepiece with digital encoder, measuring D1, D2 value, LCD directly display D1, D2 value and hardness value
- Directly select the hardness scale, test force automatically changes in test parameters
- Auto test force correction, auto test force compensation,greatly improving test force accuracy
- Can be calibrated according to standard hardness block or length scale
- The test force can be automatically corrected by standard dynamometer
- The hardness values of brinell, rockwell and vickers can be converted
- Automatic hardness conversion according to standard GB/ASTM.
- Password protection for setting parameters, more samples and test information
- U-disk of measurement data is saved in EXCEL format for easy editing and processing
Product Application：
- Suitable for hardened and surface hardened steel, hard alloy steel, casting parts, non-ferrous metals, various kinds of hardening and tempering steel and tempered steel, carburized steel sheet, soft metals, surface heat treating and chemical treating materials etc.
