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 High Voltage Holiday 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, the PCWI DC Holiday Detector 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 DC15 High Voltage Holiday Porosity Detector delivers stabilized DC output of up to 15kV and is suitable for use on thinner internal and external coatings from 150um to 3.5mm, whereas the DC30 Porosity Detector delivers stabilized 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 High Voltage Holiday 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.

Specifications

Applications

Used for detection of Coating Porosity (Pin-holes, or Holidays) in dielectric (insulation type) coatings on conductive substrates, including Concrete. Suitable for Production Pipeline Coating operations, Tank-Work and Structures. Ideal for use on Storage Tanks, Valves and Pipelines.

Housed in a fully portable ABS case, the Detectors deliver stabilized DC output of up to 30kV. Constant Current source maintains applied test voltage. Full test current at low voltages (where it is needed most) when testing at low film builds (eg: 150μm - as per AS3894.1).

Incorporating momentary-on and continuous-on switches (mounted on the front panel), allowing the units to be switched on momentarily for safety, or run continuously.

No need to swap probes to change voltage - the Detectors have Clip-on Battery Packs that must be separately charged. Fully recharged in 4 hours. Regulated DC output Fully Adjustable. Applied voltage and battery condition are continuously shown on the Liquid Crystal Display.
