Electronic Rockwell Hardness Tester　DigiRock MR2　811-120

Features：
● DigiRock MR2 analogue gauge resolution is 0.5HR, it is useful to improve the reading accuracy than traditional 1HR resolution;
● DigiRock MR2 dwell time from 1to 60s can be setup by the “time key” on the panel , it is much convenient than the setup on the manual hardness tester;
● DigiRock MR2 force knob adopts the metal material to replace the plastic, it largely improves the instrument using-life;
● DigiRock MR2 loading, dwell and unloading is buffering by electronic motor automatically, doesn't need the operator to handle it , it eliminates the human operation error maximally;
● DigiRock MR2 intenter protector is available to improve the using lifetime of indenter.


 
Application:
◆Rockwell B Scale HRB: Copper alloys, soft steels, aluminum alloys, malleable iron, etc.
