It’s a kind of heightened semi-automatic Rockwell hardness tester which is specially designed to test Rockwell hardness of metal materials. The high travel of test anvil in vertical direction makes it possible for testing of large test pieces. The process of test force loading, dwelling and unloading is finished automatically. It features easy operation, wide application range etc.


Industrial production, Inspection of product quality on processing technology. Ferrous and nonferrous metals, Hardened steel, tempered steel, annealed steel, hardened steel, sheet of various thicknesses, carbide materials, powder metallurgy materials, hardness and thermal spray coating.
