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.
Conforms to: ASTM G62-87 (1998), NACE RP0274-98,
NACE RP0490-2001, NACE RP0188-99, ASTM D4787-93 (1999), JIS
G-3491, JIS G-3492, ANSI/AWWA C214-89, ANSI/AWWA C213-94, ISO
2746:1998 & AS3894.1-2002

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.
