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

• Adjustable high-voltage output suitable for various coating thicknesses

• Both audible and visual alarm indicators for reliable fault identification

• Suitable for metallic pipes, tanks, and other conductive surfaces

• Portable and durable design ideal for field inspection

• Compatible with spring or rolling electrodes for different applications

• Ensures coating quality and prevents corrosion-related failures

• Inspection of anti-corrosive coatings on pipelines

• Quality testing of tank linings and metal surfaces

• Detection of discontinuities in paint or coating layers

• Field inspection of underground pipe coatings before installation

• Maintenance of protective coatings in industrial and marine environments
