The HR-200/300/400/500 Series Rockwell hardness testing machines from Mitutoyo offer enhanced performance with improved frames, better ergonomics and many other productivity boosting features, the company says.

These hardness testers share a new frame design that provides maximum clearance for flexible workpiece positioning and to facilitate mounting to any flat surface. The testers feature a projected-nose indenter arm designed for easy access to both interior and exterior surfaces. All HR Series hardness testers are robust and suitable for production floor as well as lab settings.

The entry-level HR-210MR Rockwell tester has a motorized major loading system to reduce the chance for operator error (common with conventional oil dash pot systems). It also features a dial indicator readout with a preset function that automatically zeros-sets the primary (minor) test force.

The mid-range HR-320MS is selectable for both Rockwell and Rockwell/
Superficial scales. It 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 dial-a-weight major load selection system.

The advanced HR-500 Series hardness testing machines offer multiple test force generation for Rockwell, Rockwell Superficial and optional Brinell hardness testing. These testers feature a projected-nose indenter arm designed for easy reach of both interior and exterior surfaces. The HR-500 uses closed-loop electronic test force control for extremely accurate loading while an auto-stop elevation table and automatic preliminary test force loading assure consistent test force generation. 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 statistical processing and process control software.
