The Pin Hole Detector is used to test the integrity of a coated surface by identifying pin holes and flaws in the coating.
Pin holes or flaws in the coating may lead to premature failure of the coating – early identification allows for corrective action to be taken. ThePin Hole Detector identifies pin holes and flaws in the coating by passing a selectable voltage of 9 volts, 67.5 volts, or 90 volts, through a wet sponge which is moved over the coated surface. The voltage will make a path through the wetting agent to the pin hole or flaw in the substrate, an audible alarm will sound and a red light will flash on the unit identifying the area for closer inspection. The application of the test is safe and does not cause burn marks or damage to the coating. The Pin Hole Detector can be carried by the operator due to its light weight and portable design. The Pin Hole Detector is supplied in a hard plastic foam filled carry case complete with 150mm broad sponge assembly, and earthing cable.
