Mitech MHV-30Z Digital Automatic

Mitech MHV-30Z Digital Automatic Hardness Tester

Product Overview

The Mitech MHV-30Z is a digital Vickers hardness tester designed with an automatic turret system to enhance efficiency in precision hardness testing. Using a diamond pyramid indenter, the device creates a small impression on the material surface, and the diagonal length of the indentation is measured using a high-resolution optical system to determine hardness.

This model features an integrated structure with advanced optics, photoelectric sensors, adjustable cold light illumination, and a user-friendly LCD interface. Its stable and accurate performance makes it suitable for use in industrial quality control, academic institutions, and research labs.

Working Principle

The Vickers method involves pressing a pyramid-shaped diamond indenter into the test material under a fixed load. After a designated time, the force is released and the diagonal of the resulting impression is measured. The hardness value is then calculated using:

HV ≈ 0.1891 × F / d²

Where:

• HV = Vickers hardness value

• F = Load applied (in newtons)

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

Operating Conditions

• Recommended Temperature: 18–28°C

• Maximum Relative Humidity: 65%

• Ideal Environment: Clean, vibration-free, and non-corrosive

• Placement: On a stable, level surface

The Mitech MHV-30Z is an advanced hardness testing instrument that delivers reliable and efficient results, making it an excellent choice for professional, academic, and industrial applications.
