◆ 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 maximum;
◆ DigiRock MR2 intenter protector is available to improve the using lifetime of indenter.
