Pinhole Detectors or wet sponge tester detects pinholes, voids, thin spots, foreign inclusions, or contamination in coatings film. Dielectric srenth of film also refered as holiday detection.

A low voltage holiday detector / wet sponge tester operation is by the application of a wet sponge to the coating. The wetting agent penetrates any pinhole and makes a conductive path through to the substrate, the pin hole detector automatically detects this conductive path and sounds an audible alarm and also gives a visual warning by a flashing red indicator that a pinhole fault has been detected. The flaw can now be marked for repair and further testing resumed. Coating on metals prevents to corrode unless a protective coating is applied. Pinholes based on wet sponge method generally caused by air entrapment that is then released from the surface, or by the entrapment of particulates (dust, sand, etc.), which do not stay in place. High voltage holiday detector is used for testing coatings above 500µm and low voltage holiday detector (Pinhole Detector ) is used below 500µm of coating on metallc substrates.
