Full automatic Rockwell hardness tester

300hrss-150 automatic full rockwell hardness tester

Model: 300HRSS-150


This automatic Rockwell hardness tester adopts close-loop control on testing process, it’s a new type hardness tester. It can clamp the sample automatically, the pressure head will clamp the sample before contact the sample, the first measure is effective, it can track and measure the impress actual depth automatically, which avoid the affect of frame & sample deformation against the impress depth, it can loading initial testing force, main testing force with no impact, and won’t be effected by the sample volume, shape and weight. The pressure head main shaft can move freely within the range of 50mm. It’s equipped with LCD display, friendly operation human interface, RS232 data interface.


Testing force close-loop control;

Auto-tracking measurement, no measure error caused by frame & workpiece deformation;

Pressure head can move up/down freely, clamp the workpiece automatically, no need for loading of initial testing force;
