Mitutoyo HR-521 Rockwell Hardness Testing Machines
Multiple test force generation for Rockwell, Rockwell Superficial and Brinell hardness. Real-time electronic test force control for accurate loading eliminates overshooting. Auto stop elevation table and automatic preliminary test force loading.
Features:
- Dolphin-nose indenter arm for easy reach of interior and exterior surfaces
- Indenter escape function for continuous testing at fixed table position. This eliminates instability caused by table retraction
- Functions: Number of values, max., min., average value, range, upper and lower limit, standard deviation, number of GO/NG evaluations, storage of 1024 values, Offset, hardness value, test condition, continuous measurement, X-R control chart, editing of 1024 values, hardness conversion value, statistical results, cylindrical correction, spherical correction, multipoint correction
