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