  • Automatic correction of load, with the force accuracy increased by a numerical level
  • Built-in hardness value correction of convex cylindrical surface.
  • RS232 interface and Built-in printer (or USB interface is optional) for data output.
  • More sample and testing information. Data stored in USB flash disk, EXCEL format, easy for editing and processing
  • Powerful data processing ability. Various hardness conversion including HR, HB, HV etc. Setting acceptable range, over-limit alert, information input of operator and sample name, etc.
  • Test results can be stored, processed and printed automatically.
  • Modular design, easy maintenance
  • Modern and beautiful appearance, stable structure


It’s suitable to determine the Superficial Rockwell hardness of ferrous metals, alloy steels and hard alloys, as well as treated layers of metal surface, such as carburized layer, nitrided layer and electroplated coating, etc.
