HR-521 Series

Mitutoyo Hardness Testers are known worldwide for their superior quality, performance and dependability. The HR-521 measures both Rockwell hardness and Superficial hardness. With real-time electronic test force control, this tester provides one of the best values in hardness testing today.

The new Mitutoyo HR521 Rockwell and Superficial type hardness tester features real-time electronic force control. Closed-loop control of the primary (Minor) and final (Major) loads permit greater accuracy and repeatability than traditional dead weight, dash-pot controlled testers. The electronic brake mechanism prevents primary force overshoot and automatically starts the test cycle. Testing scales are selected with a push of the LCD touch screen and with a push of the LCD.

Features


    • Closed-lop control of testing forces
    • Primary and final forces (loads) are applied with unparalleled accuracy and repeatability
    • Extended indenter arm reaches inside diameters and hard to reach surfaces at eye level, allowing the operator to easily see where the indenter addresses small or hard to reach parts
    • Automatic setting of preliminary test force and application of total test force
    • Indenter escape function allows automatic removal preliminary test force at end of test cycle
    • Touch screen operation with a back-lit LCD graphic display
    • Hardness scale is set automatically via the touch screen
    • Cylindrical and spherical surface compensation
    • Auto conversion to all hardness scales or tensile strength
