Holiday Detector
Porosity detectors, also known as holiday detectors, spark testers, porosimeters or jeepers, are used to ensure the longevity of coating systems by locating pin holes, air bubbles and porosity.
PCWI Compact DC Porosity Detectors are popular with coating inspectors because our unique, lightweight design makes surveying large surfaces quicker and easier. Unlike other holiday detectors on the market, these units can be operated one-handed using the shoulder or waist harness included in each kit. The unit is housed in a fully portable ABS case and supplied with a rechargeable battery pack in a clip-on style that allows you to easily substitute a spare battery, thereby reducing downtime.
The DC30 Porosity Detector delivers stabilised DC output of up to 30kV and is suitable for use on thinner internal and external coatings from 150um to 13mm. Possible applications include tanks, valves or pipelines. Both audible and visual alarms will alert when a fault is found.
PCWI Porosity Detectors are designed for long term performance in the field. To facilitate this, we stock a range of accessories for increased flexibility and replacement parts to extend the life of your detector. We recommend the purchase of a PCWI DC Crest Meter, which provides on-site calibration to ensure accurate output voltage and allow for adjustment if necessary.
