270/4 Pinhole Detector
Manufacturer: Elcometer
Part #: D270----4
Description: 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.
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.
