PCWI

The PCWI Compact is a High Voltage DC Porosity detector. They are also known as holiday detectors, spark testers, porosimeters and jeepers. These are used to ensure the longevity of coating systems by locating pin holes, air bubbles, and porosity in non-conductive coatings on conductive substrates, including concrete.

The P20 and P40 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. These models are ideal for use in moist conditions, on wet and contaminated coating surfaces.
