HR-150DT Motorized Rockwell Hardness Tester Details:


1, Introduction:


This series hardness testers, appreciated for their accuracy and easy operation, work entirely conform the international Rockwell standard. Depending on the combination of indenter type and applied total test force, a unique symbol is given to each Rockwell scale. HR-150DT and HRM-45DT feature both specific Rockwell scales HRC and HRB on a dial. The appropriate force should be adjusted manually, using the dial on the right side of the machine. After application of the preliminary force, the HR150DT and HRM-45DT will proceed with a full automatic test: Loading, duration, unloading, and will display the hardness directly.
