Holiday Detector By Caltech Engineering Services

Holiday Detector test and detect pinholes, porosity or flaws in insulated coatings on conductive substrates where coating have to provide an effective safeguard against corrosion. The portable quality control inspection instrument is used to electrically locate and fault find in defects of protective coatings. Our Holiday Detector is essential that any pinhole, porosity or flaws which will eventually lead to corrosion are detected at the earliest possible stage, preferably immediately after the coating application. Holiday detector is suitable for all types of coatings like Fusion bonded epoxy, coal tar epoxy, paints, polyester, polyurethane, pipeline tapes, Heat shrinks and Asphalt.

This versatile Holiday Detector unit can be used to inspect protective coatings applied to pipelines, tanks, pilings, fire lines or buried pipelines of conductive surface.
