PCWI Compact DC Porosity Detectors

The PCWI Compact DC Holiday Detector is a high-voltage DC device designed to detect pinholes, air bubbles, and porosity in non-conductive coatings applied to conductive surfaces such as metal or concrete. By applying a controlled high-voltage current, the detector identifies any breaches in the coating that could compromise protective performance. It is compact, portable, and suitable for field inspections, making it ideal for verifying the integrity of protective coating systems. Using this tool helps prevent corrosion, substrate damage, and coating failures, ensuring long-term durability and reliability of industrial and infrastructure coatings while meeting industry quality standards.
