The Holitech DC Holiday Detector tests and detects pinholes and flaws in insulated coatings on conductive substrates.
Where coatings have to provide an effective safeguard against corrosion, it is essential that any pinholes or flaws that will eventually lead to corrosion are detected at the earliest possible stage, preferably immediately after the coating application.
Operation is by a test voltage being applied to the coating by moving a brush electrode across the surface and where there is either a pinhole or flaw, the voltage will spark through the coating, a red indicator will flash and an audible alarm will sound. The detected flaw can be marked for subsequent repair, and testing resumed for the remaining surface area. The Holiday Tester complies with International Standards: ISO 2746, BS 1344-11, ASTM G 6, ASTM G 62, ASTM D4787, ASTM D5162, NACE RP 04901, NA
