Tablet Hardness Tester Twin Rockwell Hardness Testing Machine with Rockwell and Superficial Rockwell Test Function


Application range:

1) Suitable for quenched steel, tempered steel, annealed steel, cold and hard casting, malleable cast iron, hard alloy steel, aluminum alloy, copper alloy, bearing steel etc.

2) Suitable for surface quenched steel, surface heat treating and chemical treating materials, sheet, zinc layers, chrome layers, tin layers etc.


Main Function:

HR-150/45E Double Rockwell hardness tester is a popularly-used hardness testing instrument to measure the Rockwell and superficial Rockwell hardness of the materials. It adopts the mechanism of automatic loading and unloading of the test force, the test force is regulated by the load-change hand wheel. It can select the dwell time and is very easy to use. Besides setting zero to dial, there is no man-made error. The instrument has high sensitivity and stability.
