Holiday Detector

The holiday detector is also known as a porosity detector,pinhole tester,spark tester,jeep tester or jeeper.Holiday detectors are employed in the non-destructive detection and location of pinholes,holidays,bare spots or thin points in protective coatings applied for corrosion protection over metal or concrete (conductive) surfaces.Holiday DetectorPremature corrosion of a substrate is usually due to a coating failure.A major cause is the presence of flaws in the finished coating,collectively referred to as porosity.Holiday test is used to detect holes,known as holidays or discontinuities,in a coating.Holiday testing allows the detection of even smallest coating flaws invisible to the naked eye.Holiday DetectorPremature corrosion of a substrate is usually due to a coating failure.A major cause is the presence of flaws in the finished coating,collectively referred to as porosity.Holiday test is used to detect holes,known as holidays or discontinuities,in a coating.Holiday testing allows the detection of even smallest coating flaws invisible to the naked eye.
