This tester is a popular type Rockwell hardness testing machine, the construction is firm and reliable and safe, operating convenience etc. characteristics.The adoption adds to unload automatically to experiment the dint method, protecting time of stable, dissolves artificial operation error margin, show the worth accuracy high. That degree of hardness accounts to be applicable to the black metals and have the Rockwell surname degree of hardness measurement of the color metals.It is extensive to be applicable to factory car with calculate the section.

HRM-45DT 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. The characteristics of the instrument is light testing force and therefore, leaving very small indentation.
Usage Range:Surface hardened steel, copper, aluminum alloy thin sheet, hard alloy steel, zinc layers, chrome layers, tin layers, surface hardened treating and chemical treating materials, etc.
