Tukon Microhardness Tester


The microhardness tester works by aligning a diamond pyramid indenter under a light microscope and loading it onto a surface with a standard weight. The deeper it penetrates, the softer the material. The width of the penetration is measured under the microscope attached to the microhardness tester. It has two types of diamond indentors, called Vicker’s and Knoop. Loads can vary from 1g to 3 Kg.

Sample preparation required: flat, parallel surfaces; one metallographically polished surface. This instrument can be used for metal, adhesive, plastic or paint hardness.
