Mitech MHV50 Digital Vickers

Mitech MHV50 Digital Vickers Hardness Tester

Product Overview

The Mitech MHV50 Digital Vickers Hardness Tester is a precision instrument designed to measure the hardness of various materials, especially small, thin, coated, or heat-treated specimens. Utilizing the Vickers testing method, it uses a diamond pyramid-shaped indenter to create a microscopic indentation on the test surface. The diagonal length of the indentation is then measured to calculate the hardness value.

This device combines a high-magnification optical system, adjustable cold light source, and high-precision photoelectric sensors in a robust digital design. It delivers consistent and accurate results, making it ideal for use in metal manufacturing, electronics, quality control, education, and research applications.

Working Principle

The Vickers hardness testing method involves pressing a diamond-shaped pyramid indenter into the material’s surface with a specific force. After the force is removed, the lengths of the indentation’s diagonals are measured using the optical system. The hardness value is then calculated using the following formula:

HV ≈ 0.1891 × F / d²

Where:

• HV = Vickers hardness value

• F = Test force (in newtons)

• d = Average of the two diagonals of the indentation (in millimeters)

The Mitech MHV50 is a versatile and reliable solution for advanced microhardness testing across industrial, academic, and laboratory environments
