The Tukon 2500 Vickers/Knoop Hardness Tester measures the mechanical hardness of materials. The Vickers/Knoop microhardness test is particularly suitable for small parts, very brittle materials, or thin sheets, where only a slight indentation is required for testing purposes. The test force range is 10 g to 1000 g. Hardness testing involves using a known load and a known indenter shape, which is then pressed into a material. The depth of penetration of the indenter is proportional to the hardness of the material. Hardness data can be used to infer other mechanical properties of the material.
