Abstract
A technoscope for checking for damage, especially a crack, in a surface of a cavity in a technical component, is arranged not only to establish the area of damage but also to measure the depth of a damaged area. To this end, the technoscope has a measuring attachment comprising a measuring probe with two electrodes for straddling the damaged area, and being supported in the cavity by a support element. The depth of the damaged area is measured by means of a depth measuring instrument sensitive to the disturbance of current flow between the electrodes, and the potential difference resulting therefrom.
