Hardness testing machines are configured for automated testing in production lines. Standardized Rockwell or Super Rockwell testing methods can be selected, and the test load range is between 15-150 kg. It is not only possible to measure steel parts but can also carry out the testing of aluminum components directly after heat treatment. Each machine consists of the hardness testing module and a separate control unit, which can be placed in a control box. In manual mode, the operation is carried out via the control unit. Automatic operation uses input and output switches.
