Mitech MHBRV-187.5 Hardness Tester

Mitech MHBRV-187.5 Electric Multifunctional Hardness Tester

Product Overview

The Mitech MHBRV-187.5 is a versatile electric multifunctional hardness tester designed to support three major hardness testing methods: Brinell, Rockwell, and Vickers. This all-in-one device provides an efficient and accurate solution for material hardness evaluation across a wide range of metallic components. By combining mechanical precision with modern features like a displacement sensor and cold light source, the MHBRV-187.5 is ideal for both industrial quality control and research applications.

Built with a robust structure and intuitive controls, the tester allows operators to switch easily between testing methods. Rockwell hardness values can be read directly from a high-precision dial gauge, while Brinell and Vickers results can be converted from measured indentations. The unit conforms to both national and international standards, making it a trusted tool for manufacturing, academic, and laboratory environments.

Applications

• Quality assurance and hardness control in metal manufacturing

• Failure analysis of structural and mechanical metal components

• Research and development in industrial and scientific laboratories

• Educational use in vocational schools, universities, and technical training institutions

• Testing metallic coatings and surface treatments

Working Principle

The MHBRV-187.5 determines hardness by pressing an indenter (either a steel ball or diamond pyramid) into the test surface under a specific load. Depending on the selected method:

• Brinell measures the diameter of the indentation from a steel or tungsten carbide ball

• Rockwell calculates hardness based on the depth of indentation under major and minor loads

• Vickers uses a diamond pyramid indenter to determine hardness from the diagonal length of the square-shaped mark

Each method follows specific test forces and durations, and values are either read directly or calculated via conversion tables.
