Micro vickers hardness tester is mainly used to measure micro and thin test pieces and brittle hardware. By selecting various accessories or upgrading various structures, it can be widely used in various metals (ferrous metals, non-ferrous metals, castings, alloy materials, etc.), metal structure, metal surface processing layer, electrodeposited layer, hardened layer (oxidation, various infiltration layers, coating coating), heat treatment specimens, carbonization tests Test of brittle and hard nonmetallic materials such as glass, agate, artificial gem and ceramics. Multi point measurement of precise positioning, in-depth measurement and analysis of indentation, test and analysis of penetration coating, test and analysis of hardness gradient, observation and research of metallographic structure, measurement and analysis of coating thickness, etc. It is a necessary testing instrument for quality control and material research of laboratory quality inspection department and Metrology Institute.
