The defectoscope is used for the non-destructive testing of components made of different materials. As well as using optical methods, a defectoscope can detect material defects by means of, for example, ultrasound, eddy current or even magnetic fields. Be it discontinuities, voids, cracks or material inclusions, with the defectoscope these errors can be found and very precisely localized. A determination of the size of the errors is also possible.

The special advantage of the defectoscope lies in the possibility to check components whilst they are installed, even during their operation. Installations do not necessarily have to be taken down, and components can be controlled directly on site, with no need for costly and time-consuming removal work. A defectoscope therefore finds application in a wide range of areas, including e.g. mechanical engineering, pressure vessel construction, pipeline construction, aerospace engineering and rail transport
