Electric Rockwell hardness tester, controlled by a motor to load, maintain, and unload the test force, with selectable load holding time. Easy and quick to operate, no human error, highly sensitive and stable.
Measurement of Rockwell hardness for heat-treated materials such as hardened and tempered materials, including cemented carbide, carburized steel, quenched steel, surface-hardened steel, hard cast steel, aluminum alloys, copper alloys, malleable castings, mild steel, quenched and tempered steel, annealed steel, bearings, and other materials.
The LCD digital display indicates the degree directly, ensuring accurate measurement and reducing human error. Data can be stored directly and output for printing.
Electric control motor adds and removes experimental force, with a load holding time of 1-30 seconds, adjustable for greater convenience and speed.
Specialized indenters equipped with diamond indenters and steel ball indenters can be directly replaced when measuring hard metals and soft metals.
Important Pre-Purchase Notice: The input voltage for electric Rockwell hardness testers is 220V.
