Rockwell hardness tester HR-150B

manualmechanicalelectric

Product overview
The HR-150B high-body Rockwell hardness tester (mechanical lever and weight-loading) and its electric-loading variant HRD-150B are designed for hardness measurement of large workpieces. The elevated frame (maximum test height 400 mm) and robust loading options make the instrument suitable for workshop and laboratory quality control. HR-150B provides manual mechanical loading; HRD-150B adds electric loading for automated operation.
