Holiday Detectors

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 detectors are suitable for production pipeline coating operations, tank work and structures.

We proudly offer a full range of Holiday detectors with the best prices and quick deliveries. If you require any additional information, please contact us by e-mail, chat or telephone and a product specialist will be glad to assist you.
