I. Features
The automatic microhardness tester is mainly used to measure tiny, thin specimens, and brittle hardware. It can be widely used in various metals (ferrous metals, non-ferrous metals, castings, alloy materials) by selecting various accessories or upgrading various structures. etc.), metal structure, metal surface processing layer, electroplating layer, hardened layer (oxidation, various infiltration layers, coating layer), heat treatment specimens, carbonized specimens, quenched specimens, tiny parts of phase inclusions, glass, agate , artificial gemstones, ceramics and other brittle and hard non-metallic materials testing. It is especially suitable for mass measurement of the hardness gradient distribution curve of workpieces, and hardness testing of specified parts.
