This machine is a desktop Rockwell hardness tester, which adopts the Rockwell measurement principle. It is used for the hardness testing of carbon steel, alloy steel, cast iron, non-ferrous metals and engineering plastics. It features high accuracy, wide measurement range, automatic switch of test forces, automatic loading and unloading of main test force, digital display, and automatic printing of test results or communication with an external computer. It can be widely used in the measurement, scientific research and production of metrology, machinery manufacturing, metallurgy, chemical industry, building materials and other industries.
