HBRVD-187.5D1 Brinell Rockwell &Vickers Hardness Tester using rotary power conversion and optical measuring system in the body microscope equipped with measuring devices. As a result of using low-speed synchronous motor control unloaded automatic test force, tester force dwell time through change of the delay potentiometer, with the exception of Rockwell hardness test requirements of artificial dial zero, the Brinell hardness test and Vickers hardness test through microscopes and measuring the diameter of the indentation diagonal, not man-made error of the operation.
The hardness tester has high test accuracy, simple, sensitive and easy to use, reliable the Pressure Selecting changed , showing the value of stability, applicable to the wide range of factory floor , Laboratories, universities and research institutions.
