Rockwell Hardness Tester
Rockwell Hardness Tester
Rockwell and Rockwell Cum Brinell Hardness Testing Machine
Universal Hardness Testers, equipped with a set of six ball bearings guide device, for the plunger/spindle, automatic load selection for 15, 20, 30, 40, 45, 50, 60, 100, 125, 150, 187.5 and 250 kg for conducting Vickers, Brinell, Standard Rockwell and Superficial Rockwell method tests.
The standard accessories includes all the required indentors and two microscopes separately one for the measurement of ball indentation dia for Brinell method test, and the other for the Vickers indentation diagonal measurement for Vickers method test. The least count of 100 x Vickers microscope also supplied with illumination device is 0.01mm directly on the scale and 0.001mm with estimation.
