PCWI Low voltage Pinhole Detector

The low-voltage Holiday Detector is designed to identify pinholes, voids, and discontinuities in protective coatings using the wet sponge method. Available in selectable models of 5, 9, 67, and 90 volts, it allows precise detection for a range of coating thicknesses and types. The detector operates by passing a low electrical current through a wetted sponge applied to the coated surface; any breach in the coating completes the circuit, triggering an alert. Ideal for both field and laboratory inspections, this tool ensures coating integrity, helping prevent corrosion or substrate damage and maintaining high-quality standards in protective coating applications.
