Holiday Detector

Newly designed latest technology Holiday Detector test and detect pinholes, porosity or flaws in insulated coatings on conductive substrates. HD-05 Holiday Detector has range of 0-5KV DC. Holiday Detector meets international standards.The portable digital holiday detector is used quality control inspection instrument is used to electrically locate and fault find in defects of protective coatings. Audible and visual alarms are activated when a flaw is detected. 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 unit can be used to inspect protective coatings applied to pipelines, tanks, pilings, fire lines or buried pipelines of conductive surface. A test voltage is applied to the coating by moving a brush probe across the surface and where there is either a pinhole or flaw the voltage will spark through the coating at the flawed location a red flashing indicator will flash and an audible alarm will sound the detected flaw can now be marked for subsequent repair and testing resumed for the remaining surface area, if no flaws are detected the test will therefore be non-destructive.
