(Mitutoyo: Aurora, IL) -- The new series of Rockwell hardness testing machines—HR-200/300/400/500—from Mitutoyo America Corp., provider of measurement and inspection solutions, offer enhanced performance with improved frames, better ergonomics, and many other productivity boosting features. And they are economical to own and operate, making HR machines the value leaders in Rockwell hardness testing.

Mitutoyo HR-200/300/400 Series hardness testers share a new frame design that provides maximum clearance for flexible workpiece positioning and facilitates mounting to any flat surface. Mitutoyo HR-500 Series testers feature a projected-nose indenter arm for easy access to both interior and exterior surfaces. All HR Series hardness testers are robust and suitable for the production floor as well as lab settings.

Even the entry-level HR-210MR Rockwell tester is feature-packed. It has a motorized major loading system to reduce the chance for operator error (common with conventional oil dash pot systems). The result is improved accuracy and repeatability. In addition, the HR-210MR features a dial indicator read-out with a preset function that automatically sets to zero the primary (minor) test force.
