Product Details

MBMRV-187.5 Universal Hardness Tester with all-purpose hardness appearance and easy operation, integrating the hardness value of Brinell, Superfacial Rockwell, Rockwell, Vickers into one machine. It uses low-speed servo motor control automatic micro-discharge test force, test force dwell time delay potentiometer can be adjusted to achieve non-section, in addition to dial manually to zero, there is no human operator error. Widely used in factories measuring department, laboratories, universities and research institution.
