Mitech MHV-10 Vickers Hardness Tester

Mitech MHV-10 Vickers Hardness Tester

Product Overview

The Mitech MHV-10 Vickers Hardness Tester is a high-precision device designed for measuring the hardness of small specimens, thin materials, surface coatings, and heat-treated components. Operating based on the Vickers indentation principle using a diamond-shaped pyramid indenter, this tester accurately evaluates material hardness by measuring the length of the indentation diagonals.

Working Principle

The Vickers hardness test applies a static load to a diamond pyramid-shaped indenter that presses into the specimen’s surface. After a fixed duration, the load is removed, and the diagonal lengths of the indentation are measured. The Vickers hardness value (HV) is calculated using the formula:

HV ≈ 0.1891 × F / d²

Where:

• HV = Vickers hardness value

• F = Applied test force (in newtons)

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

Operating Conditions

• Ideal Operating Temperature: 18 – 28°C

• Relative Humidity: ≤ 65%

• Installation Environment: Vibration-free, clean, non-corrosive environment

• Surface Requirement: Stable and flat installation platform
