Mitech MHV-1 Micro Vickers

Mitech MHV-1 Micro Vickers Hardness Tester

Product Overview

The Mitech MHV-1 Micro Vickers Hardness Tester is a precision instrument designed for microhardness testing of small, thin specimens, surface coatings, and heat-treated materials. It operates by pressing a diamond-shaped indenter into the test material and measuring the diagonal length of the indentation to calculate the hardness value.

Combining a high-magnification optical system, photoelectric sensing technology, and a large LCD screen, the MHV-1 ensures accurate measurement, intuitive operation, and clear display of test results. This tester is ideal for applications in quality control, research, and material analysis within the metalworking, electronics, watchmaking, and academic sectors.

Working Principle

The Vickers test method applies a defined force through a diamond pyramid-shaped indenter onto the material’s surface. After the force is removed, the diagonals of the resulting impression are measured. The Vickers hardness value (HV) is calculated using the following formula:

HV ≈ 0.1891 × F / d²

Where:

• HV = Vickers hardness value

• F = Test force in newtons (N)

• d = Average diagonal length of the indentation in millimeters (mm)

The Mitech MHV-1 offers high-resolution microhardness testing with a compact, lab-ready design, making it a reliable tool for precise material evaluation.
