Product details
product description
The HRM-45DT electric surface Rockwell hardness tester adopts an automatic loading and unloading test force mechanism, and the test force is obtained by the rotation of the variable load handwheel. The holding time can be selected, and the operation is simple and fast. Except for the dial being zeroed, there is no human operation error, and it has high sensitivity and stability.
Application scope:
Suitable for surface quenched steel, material surface heat treatment and chemical treatment layers, copper, aluminum alloys, thin plates, galvanized, chrome plated, tin plated materials, bearing steel, cold hard castings, etc
