The PCWI Compact Holiday Detector is a High
Voltage DC Porosity detector also known as holiday detectors,
spark testers, porosimeters or 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.

holidays) in dielectric (insulation type) coatings on
conductive substrates, including concrete.
Suitable for production pipeline coating operations,
tankwork and structures. Ideal for use on storage tanks,
valves and pipelines.
