Vickers Hardness Tester

About Vickers Hardness Tester

A Vickers Hardness Tester is a precision material testing instrument used to measure the hardness of metals and other materials by indenting the surface with a diamond pyramid indenter under a specific load. It provides highly accurate and consistent hardness values, making it suitable for both micro and macro hardness testing applications.

This machine is widely used in metallurgical laboratories, heat treatment plants, automotive industries, research institutions, and quality control departments for material evaluation and inspection.

Key Features

• High-precision diamond pyramid indenter (136 angle)
• Wide load range for micro and macro hardness testing
• Digital / analog display system (model dependent)
• Motorized or manual load application system
• Optical measurement system with microscope
• Rigid and vibration-free frame construction
• Adjustable dwell time and test parameters
• Conforms to ASTM / ISO hardness testing standards

Working Principle

The Vickers hardness test works on the principle of indentation hardness measurement. A diamond-shaped indenter is pressed into the material surface under a known load. After removing the load, the size of the indentation is measured using a microscope, and hardness is calculated based on the diagonal length of the impression.

Applications

• Hardness testing of metals and alloys
• Heat-treated components evaluation
• Thin materials and coatings testing (micro hardness)
