Pinhole detection is essential to monitor the integrity of the protective coating from its initial application to the end of its service life. Pinholes are caused by air entrapment, which is then released from the surface, or by the entrapment of particulates (dust, sand etc.) which do not stay in place. Elcometer offers a range of Pinhole Detectors from the low cost UV Pinhole Detector Flashlight to the full Pinhole Detector Inspectors Kit.

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.
