These series hardness testers are known far and wide for their economical and practical features, reliability and easy operation. Manually set the zero position during testing. There are two kinds of testing method: Rockwell standard (60,100,150kg) and Superficial Rockwell standard (15,30,45kg). The testing result values can be read out directly from the dial. Rotate the Load-Change-Hand-Wheel at the right side of the tester to select the test load and it does not need the power source.
Model HR150A serves to measure the hardness value of hard alloy, carburized steels, quenched steels, hard cast irons, soft copper, aluminum alloy,copper alloy and malleable irons.
