Vickers Hardness Tester
Category：Material Strength Tester
Introduction
The Vickers Hardness Tester is a high-precision instrument used for measuring the hardness of various materials, including ferrous and non-ferrous metals, thin plastic sections, glass, ceramics, agate, precious stones, and more. It applies a diamond pyramid indenter to measure the material’s resistance to indentation and calculates the Vickers hardness value. This instrument is widely used for testing hardened layers, carburized layers, and other surface-treated materials in various industrial and research applications.
Application
Suitable for ferrous metal, non-ferrous metals, IC thin sections, coatings, ply-metals; glass, ceramics, agate, precious stones, thin plastic sections etc.; hardness testing such as that on the depth and the trapezium of the carbonized layers and quench hardened layers.

FAQ
1.What materials can be tested with this instrument?
This instrument is suitable for testing metals, non-metals, thin plastics, glass, ceramics, and more.
2.How do I choose the right test force?
The appropriate test force is selected based on the material’s hardness. Harder materials require higher test forces.
3.Is the hardness value calculation automatic?
Yes, the system automatically calculates and displays the hardness value once the diagonal of the indentation is entered.
4.How do I ensure test accuracy?
Ensure that the sample surface is clean and flat, and select the appropriate test scale and load control for precise results.
