HR-320MS/430MR/430MS Series 963-Rockwell Hardness Machines

Series 300
Features
  • The new frame design alllows the full 7.1” of specimen capcity without the need to cut a whole in the table.
  • Simple to operate; The digital HR320 model uses a flashing bar graph to indicate when the initial test force has been reached.
  • 430 models feature automatic brake and automatic start function that prevents overloading and begins test cycle. The HR430 model also includes the dial a weight system for easier load selection.
  • All models are complete with Flat and VEE anvils, diamond and 1/6” carbide ball indenters, 2 HRC and 1 HRBW Rockwell blocks (MR models)s or 3 Rockwell blocks and an HR30N and HR30TW for MS testers
