HRM 45D of Motorized superfical Rockwell hardness tester
HRM 45D of Motorized superfical Rockwell hardness tester features high measuring accuracy, veliable performance and applicable to wide fields. By adopting the motor driven automatic loading and unloading technique, that thoroughly eliminates human error in those operations. Model HRM-45DT serves to determine the superficial Rockwell Hardness of hardmetals, carburized, nitrided layers, and other chemical freating layers, it is also used to for hardness test of thiner pieces.
