Manual Superficial Rockwell hardness tester(HR-45A)

 

Main function and features

1,  It is adapted to test the thin parts and surface of the metal

2,  The machine shell is formed by cast iron, stable structure and it is not easy to be out of shape

3,  The dial reads the hardness value directly, indicator responses sensitively, show the hardness value accurately, which is more than national standard

4,  Rotate the loading wheel, it can easy to adjust the three loading test force to choose the hardness unit

5,  This model HR-45A is no need to use the electric power, which can use in different conditions; it is economic and practical superficial Rockwell hardness tester.

 

Main application

 Surface hardening steel, copper, aluminum alloy thin plate; strip steel, hard alloy steel, galvanization, chroming, and tinplating, heat treatment of the material surface and chemical surface treatment of different kind of material.
