Portable Large C Clamp Rockwell Hardness Tester Meter Sclerometer PHR-8-10.


  • Can accurately test large and medium size workpieces on site
  • The testing principle and accuracy meet the requirements of ISO 6508 and ASTM E110, tested by National Institute of Metrology and the error is within 1.5 HRC, same as the bench type.
  • First clamp the workpiece, then apply the test force, stable testing with high repeatability and precision.
  • Used for large and medium size moulds, shafts rollers, tubing and all kinds of metal parts.
  • Used for production inspection and acceptance inspection, replacing rebound type hardness testers with lower precision
  • Traceable standard hardness block
  • Indenter inspected with standard Rockwell hardness tester.
  • Test force calibrated with load cells directly traceable to national secondary benchmark
