HR-150DT type Rockwell hardness tester is used to test Rockwell hardness of metallic materials specifically semi-automatic Rockwell hardness testers. Test force, load, unload auto-complete and easy operation.

The scope of
Hardened steel, tempered, annealed steel, chilled casting, malleable cast iron, aluminum, copper bearing steel.

HR-150DT Motorized Superficial Rockwell Hardness Tester adopts motorized testing method. Its testing force can be loaded, kept and unloaded automatically. Avoid man-made error and easy to use. It is therefore, welcomed by many users.

Usage Range:
Hardened and surface hardened steel, hardening and tempering steel, tempered steel, cold and hard casting parts, forging pats, hard ally steel, aluminum alloy, bearing steel, carburized steel sheet, etc.
