How does a microhardness tester demonstrate its uniqueness in the determination of non metallic materials?

Microhardness testers demonstrate their unique value in the hardness measurement of non-metallic materials. Especially for brittle materials such as glass, ceramics, and minerals, the microhardness test not only provides accurate hardness data but also allows for in-depth research into the plasticity and brittleness characteristics of the material through the observation of the indentation shape. In addition, the hardness scale conversion function makes conversion between various hardness scales simple and fast, greatly improving the efficiency and accuracy of hardness measurement for non-metallic materials.
