Feature & Use:

  • Electric loading without weights, closed-loop control, unnecessary for installing weights and debugging, high precision sensor.
  • 8” Large touch screen interface, easy operation, multi-language versions
  • Choose hardness scale directly and test load will change automatically in testing parameters
  • All Rockwell scales, total 15 types
  • Automatically apply the initial load and main load
  • Automatic correction of high, medium and low hardness values
  • 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 Rockwell hardness of ferrous and nonferrous metals, hardened steel, tempered steel, annealed steel, hardened steel, sheet of various thicknesses, carbide materials, powder metallurgy materials and thermal spray coating.
