Holiday / Porosity Detector

The holiday detector is also known as a porosity detector,
pinhole tester, spark tester, jeep testers or jeeper.

Porosity or 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 and concrete (conductive) surfaces. Detectors are suitable for production pipeline coating operations, tankwork and structures.

Compact DC Holiday Detector
The Compact DC Holiday Detector is small and lightweight with a clip-on battery pack and features digital display of applied voltage, constant test current, fully adjustable voltage and sensitivity controls. It can be used in most applications including pipelines, steel structures and tankwork. Commonly known as holiday detectors, spark testers or jeepers. Complies with the requirements of AS3894.1-2002. CE Compliant. More info...

Compact Pulse Holiday Detector
Holiday Detector with fully adjustable, regulated 'pulsed' output up to 20kV, 40kV or 60kV. All pulse porosity detector models can be used for porosity and holiday testing of carbon impregnated coatings such as carbonated rubber, thick coatings such as rubber linings and on ‘plastic’/fibreglass type coatings likely to become electrostatically charged. The Pulse 20kV & 40kV models are ideal for use in moist conditions, on wet and contaminated coating surfaces. The Pulse 60kV model is the only portable battery operated model on the market capable of generating voltages from 10,000 to 60,000 volts. More info...

Compact Inspector Holiday Detector
Superior porosity holiday detector. Portable single hand held unit, designed with the inspector in mind. Unit weighs only 460g. Two models: up to 10kV; or up to 20kV using the extended use power pack. More info...

Compact Wet Sponge Tester
Uses the wet sponge method to detect pinholes in coatings. Models available: 9, 67,5 and 90 volt Selectable and 67.5 volt fixed. Large sponge head & telescopic handle which extends to 1.2m (47"). We highly recommend high voltage holiday and porosity testing in lieu of wet sponge testing when working with coatings over 150 µm, or coatings in corrosive environments. Complies with the requirements of AS3894.2-2002 (Wet Sponge Testing). CE Compliant. More info...
