Abstract

Two new instruments from Elcometer Instruments of Manchester, the 204 and 269, detect pinholes and flaws in oatings non‐destructively from 0–500 microns on any conductive substrate. Battery powered, both units are lightweight, easy and quick to use and reliable in the field. Using the well‐proven ‘wet sponge’ method — a low voltage is passed through a damp sponge which is run across the coating to be tested. If a flaw is encountered the current is conducted to the substrate and an audio alarm sounds.
