Feature & Use:

  • Automatic rising of sample, automatic testing process, put the sample on work table, press the “Start” button to obtain the hardness value of each sample directly.
  • Electric loading without weights, closed-loop controlling system, unnecessary for installing weights and debugging. High-precision sensor.
  • Touch screen interface, easy operation, select hardness scales directly and test force will change in testing parameters accordingly.
  • Automatic correction of high, medium and low hardness numbers in accordance with standard hardness block.
  • Test force can be automatically corrected by standard force meter.
  • Automatically apply the initial load and main load.
  • All Rockwell scales, total 15 types.
  • Powerful data processing functions. Various hardness scales conversion of HR, HB, HV etc. Acceptable range setting, over-range alert, operator name and sample name input etc.
  • More information of sample and testing. Data stored in USB flash disk, EXCEL format, easy for editing and processing.
  • Modern and beautiful appearance, stable structure.
  • Larger sample space, huge sample stage.


Industrial production, Inspection of product quality on processing technology.
