HR Series Rockwell Hardness Testers with Advanced Digital Display and Automation (AI)

Rockwell

Mid-Range HR-320MS, HR-430 Twin Models, and Measurlink® Software Integration for Precision Testing

The mid-range HR-320MS is selectable for both Rockwell and Rockwell/ Superficial scales. The HR-320MS features a high contrast LCD digital display, conversions for all common scales, and a motor driven loading sequence. 

The HR-430 Series is available in Rockwell-only or Rockwell/Superficial Twin Tester models. HR-430 models feature an automatic brake-and-start feature to prevent overloads during the minor load cycle and to initiate testing when the proper load is achieved. HR-430 testers also include the convenient dial-a-weight major load selection system.  

All HR Series hardness testers can perform Brinell hardness tests when equipped with available optional accessories: a Brinell indenter, weight set and measurement microscope.   

HR Series Rockwell hardness testing machines support Measurlink®, Mitutoyo proprietary statistical processing and process control software. Measurlink® performs measurement data analysis and provides real-time display of measurement results for SPC Software and other management routines. The program also provides archiving and can be linked to a higher-level network environment for enterprise-wide functionality.
