HRS-150 Digital Rockwell Hardness Tester

(Large screen, built-in printer)

Introduction: Hardness is one of the important indexes of material mechanical properties, and hardness test is an important means to judge the quality of metal materials or parts. Since the hardness of metal has a corresponding relationship with other mechanical properties, most metal materials can approximate other mechanical properties such as strength, fatigue, creep and wear by measuring the hardness. The digital Rockwell hardness tester has a novel large screen display, which has good reliability, operability and intuitiveness. It is a high-tech product integrating electromechanics. Its main functions are as follows: Selection of Rockwell hardness scale; Selection of plastic Rockwell scale (special requirements, supplied by contract); Conversion value between hardness scales; Hardness test result printout; RS232 super terminal setting for users extensions. It is suitable for hardening, quenching and tempering, annealing, chilled castings, malleable castings, hard alloy steel, aluminum alloy, copper, bearing steel, etc. It is the ideal hardness for determining the Rockwell hardness of ferrous metals, non-ferrous metals and non-metallic materials. meter.
