ABS Plastic Holiday Detectors, Color : Black, Display Type : Digital

A Holiday Detector, also known as a Porosity Detector or Pinhole Detector, is an essential inspection instrument designed to detect pinholes, cracks, and discontinuities in protective coatings applied over conductive substrates. The instrument functions by applying a high voltage across the coated surface using a probe. When the probe encounters a defect in the coating, an electrical path is established, triggering an audible and/or visual alarm.

These detectors are widely utilized in quality control for coatings on pipelines, tanks, and metal structures to ensure the integrity of anti-corrosive layers before installation or service use.

• Detects pinholes, cracks, and coating defects quickly and accurately
