JG-100 Rockwell Hardness Tester Rockwell Hardness Tester Hardness Tester

Equipment Usage:
  • It's suitable to determine the Rockwell hardness of ferrous, non-ferrous metals and non-metal materials. It can be widely applied in the Rockwell hardness testing for heat treatment materials, such as quenching, hardening and tempering, etc.;measurement for curved surface is steady and reliable.


  • Steady and durable, high test efficiency;
  • HRA, HRB, HRC scale can be read direct from the gauge;
  • Optional for other Rockwell scale (HRD,HRF,HRG,HRH,HRE,HRK,HRL,HRM,HRP,HRR,HRS,HRV)
  • Adopts precision oil pressure buffer, loading speed can be adjusted;
  • Manual testing process, no need for electric controlling£»
  • It's steady and reliable for testing of curved surface£»
  • Precision conforms to the Standards of GB/T 230.2, ISO 6508-2 and ASTM E18£»
