This compact and handy gauge is designed for non-destructive, fast and precise coating thickness measurement. The principal applications lies in the field of corrosion protection. It is ideal for manufacturers and their customers, for offices and specialist advisers, for paint shops and electroplaters, for the chemical, automobile, shipbuilding and aircraft industries and for light and heavy engineering

  • DT-156 gauges are suitable for laboratory, workshop and outdoor use
  • The probe can work on both principles, magnetic induction and on the eddy current principle. One probe only is required for coating measurement both on ferrous and non-ferrous metal substrates. It is adaptable to specific tasks: i.e. they can be used on special geometries or on materials with special properties.
