A holiday detector is a device used to inspect nonmoving equipment or a metallic surface to ensure structural integrity
and assist with corrosion prevention efforts. Holiday detectors are commonly used to resolve the rate of premature coating
failures on a metallic surface by sensing the presence of coating faults and discontinuities (holidays) and the porosity of the
coating.Holiday detectors are used to inspect pipelines, operational plant equipment and other metal surfaces by being manually
moved along the surface being going to under test. They are used to keep out properties such as protective coating thickness,
cracks, and salt and moisture present in environments as concentration. In commercial plant or factory consisting coating
methods for the application of a layer of respective material consider to a substrate, like paper, fabric film, foil, plastic, or sheet
stock , PVC material..
