Model HR-150DT, HRM-45DT Motorized Rockwell Hardness Tester
This series of hardness testers features high measuring accuracy,veliable performance and applicable to wide fields. By adopting the motor driven automatic loading and unloading technique, that thoroughly elirninates human error in those operations.
Model HR-150DT serves to measure the hardness of hardmetals. carburized steels. quenched steels. hardcast irons, mild steels. Al-alloys, Cu-alloys and malleable irons.
Model HRM-45DT serves to determine the superficial Rockwell Hardness of hardmetals, carburized, nitrided layers, and other chemical freating layars, it is also used to for hardness test of their pieces.
