MHRS-150 touch screen digital Rockwell hardness tester
MHRS-150 touch screen digital Rockwell hardness tester
Product details
Product Introduction
A hardness tester is a testing instrument used to determine the hardness of materials, and hardness testing is a means of judging the quality of metal materials or product parts. The so-called hardness refers to the ability of a material to resist the pressure of another object that does not undergo residual deformation under certain conditions. The greater the ability to resist, the higher the hardness, and vice versa, the lower the hardness.
