RM Series Economic Rockwell Hardness Tester

R(M)-150Z1 Fully-automatic digital-display Rockwell hardness tester

R(M)-45Z1 Fully-automatic digital-display Rockwell superficial hardness tester
R(M)-150ZX Fully-automatic end- quenching digital-display Rockwell hardness tester
(with X-axis mobile test bench)
Features:
Large LCD digital display, with rich menu contents, and complete functions.Fully automatic one-button operation, automatic rising of lead screw, as well as automatic loading and unloading, which is simple to operate.Automatic display of hardness number, with high precision, and small resolution in indicating value, where there are no operator errors.Automatic discrimination on minimum thickness of specimen, and with the function of out-of-threshold warning.Built-in micro printer, which can print mean, maximum and minimum hardness number, as well as their discreteness.Automatic conversion between any other hardness (HB, HV, and etc.).R (M) -150ZX is equipped with power-driven mobile test bench, and professional software, so it can carry out a multipoint test (end quenching) automatically.
In possession of two state intellectual property rights.
Application scope:
Rockwell hardness: Used to determine Rockwell hardness of ferrous metals, nonferrous metals, and non-metallic materials; suitable for measurement on Rockwell hardness of materials after heat treatment, such as quenching and tempering;
Rockwell superficial hardness: Used to determine Rockwell superficial hardness of  ferrous metals, alloy steels, cemented carbides, and after the metal surface treatment (carburizing, nitriding, and electroplating);
