Motorized Hardness Tester

Motorized Hardness Tester Introduction

Hr-150dt Rockwell hardness tester is famous for its accuracy and easy operation, and its work fully conforms to the international Rockwell standard. Each Rockwell grating ruler has a unique symbol, depending on the combination of the indenter type and the total test force applied.

Hr-150dt has a specific Rockwell scale HRC and HRB on the dial. The appropriate force should be adjusted manually using the dial on the right side of the machine. After prestressing, hr-150dt will conduct full-automatic test: loading, duration, unloading, and directly display hardness
