Working Principle

The Vickers method operates by pressing a diamond pyramid-shaped indenter into the material’s surface with a specific force for a set period. After the force is removed, the diagonals of the resulting square-shaped indentation are measured. The Vickers hardness value is then calculated using the formula:

HV ≈ 0.1891 × F / d²

Where:

• HV = Vickers hardness value

• F = Applied force in newtons

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

Operating Conditions

• Operating temperature: 18～28°C

• Relative humidity: ≤ 65%

• Environment: Free of vibrations and corrosive gases

• Installation: Place on a stable, flat surface

The Mitech MHV-Z Series is an ideal solution for users who require precise, automated, and versatile microhardness testing capabilities across a wide range of materials and applications.
