Особенности и применение

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.
