Working Principle

The Vickers test method involves pressing a diamond-shaped, square-based pyramid indenter into the specimen’s surface with a specific force for a fixed duration. After the load is removed, the diagonals of the resulting indentation are measured using a microscope. The Vickers hardness value (HV) is calculated using the formula:

HV = 0.1891 × F / d²

Where:

• HV = Vickers hardness value

• F = Applied force (in newtons)

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

Operating Conditions

• Temperature: 18–28°C

• Relative humidity: ≤ 65%

• Environment: Free from vibrations and corrosive gases

• Installation: Should be placed on a flat, stable surface

The Mitech MHV-50Z is a powerful and user-friendly solution for precise hardness testing in both routine inspection and high-level research environments.
