More Information
Summary:A hardness testing apparatus has an indenter shaft having an indenter at a top thereof, a force motor for moving the indenter shaft in its axial direction and applying a predetermined test force to a sample through the indenter, an external force detection section for detecting an external force applied from outside of the hardness testing apparatus to the indenter shaft when the indenter shaft is moved by the force motor, and an external force adjustment and control section for controlling the force motor to apply the predetermined test force to the sample while deadening the external force detected by the external force detection section.
