Mitech MHBRVU-187.5 II Advanced Optical

Mitech MHBRVU-187.5 II Advanced Optical Hardness Tester

Product Overview

The Mitech MHBRVU-187.5 II is an advanced optical hardness tester that integrates Brinell, Rockwell, and Vickers hardness testing methods into one robust system. This multifunctional device operates on the principle of pressing a diamond or carbide indenter into the test material’s surface to create an indentation, then measuring either the depth or the diameter of the impression to determine hardness.

Designed for precision and versatility, the tester features a high-resolution optical projection screen that allows direct reading of Rockwell hardness values, while Brinell and Vickers values are obtained using standard conversion tables. With a modern interface, semi-automatic load control, and adjustable lighting, this instrument meets the rigorous demands of industrial and laboratory testing.
