HR-521 (L) /523 (L) Series 810-Rockwell Type Hardness Testing Machines

Series 810
  • Multiple test force generation for
    Rockwell, Rockwell Superficial and Brinell hardness.
  • Dolphin-nose indenter arm for easy reach of interior (min. ø40mm/ø22mm*) and exterior surfaces. *When using an optional diamond indenter (19BAA292).
  • Real time electronic test force control for accurate loading. This perfectly eliminates load force overshooting.
  • Indenter escape function for continuous testing at fixed table position. This eliminates instability caused by the table retraction.
  • Auto-stop elevation table and automatic preliminary test force loading to provide stable test force generation.
  • Complete with one flat and VEE anvil, diamond and 1/16” carbide ball indenters, 2 HRC and 1 HRBW Rockwell test blocks and an HR30N and HR30TW test block.
