Mitutoyo HR-521

• 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

Force Control:

Rockwell/Rockwell superficial hardness testing.  Continuous testing.

Cylindrical/spherical surface compensation, data offset.

Hardness conversion (HV, HK, HRA/B/C/D/F/G/15T/30T/45T/15N/30N/45N, HS, HB, HBW, tensile strength).

OK/± NG tolerance judgment, measured data editing, data memory (max 1024 data).
