PCWI

Precision Instrumentation

PCWI designs and manufactures world leading range of compact porosity detectors, often called holiday or pin hole detectors. PCWI was one of the first companies in the world to develop compact, portable, porosity detectors allowing you to take them where you need them without the heavy lifting.

Compact DC Porosity Detector

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.

Compact Pulse Detector

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.
