Testing for pînholes with the wet sponge method
Pinholes are caused by air entrapment, which is then released from the surface, or by the entrapment of particulates (dust, sand etc.) that do not stay in place. The Elcometer 270 range utilizes the wet sponge technique and has been designed to set a new standard for wet sponge pinhole detectors – a high-quality, low voltage detector with similar accessories to a high voltage spark tester. They are available both as an individual gauge and as a pinhole inspection kit. Elcometer also offers the 260 UV Pinhole Flashlight for a quick, low-cost method of testing coatings for pinholes.
A low voltage is applied to a moist sponge. When the sponge moves over a coating flaw, liquid penetrates to the substrate and completes an electrical circuit, setting off the alarm. The wet sponge technique is suitable for measuring insulated coatings less than 500 µm or 20 mil on conductive substrates and is ideal for powder coatings and other coatings where the user does not wish to damage the coating.
