MHRS-150 MHRS-45 MHRS-150/45 Touch Screen Digital Rockwell / Superficial Rockwell / Double Rockwell Hardness Tester
Hardness tester is used to determine the hardness of materials, and hardness test is a means to judge the quality of metal materials or parts of products. The so-called hardness is the ability of a material to resist the indentation of another body without residual deformation under certain conditions. The greater the resistance, the higher the hardness, and vice versa, the lower the hardness.
MHRS-150, 45, 150/45 touch screen digital display Rockwell, surface Rockwell, double Rockwell hardness tester is a novel appearance, stable performance of high-tech products. Visual digital display and computer control, stable performance, is a set of mechanical and electrical integration of high-tech products, can carry out Rockwell scale hardness testing.
