Holiday Detector - PinHole Detector

Description

Holyday detectors – non destructive testing devices used to inspect coatings over conductive substrates. Coatings exposure to atmospheric agents leads to a natural decaying of their protective feature and even pin holes not detectable by sight may compromise the underlying structure. Holiday detectors are able to highlight, both acoustically and visually, even the smallest flaw in order to evaluate the coatings’ effectiveness. This instrument is widely used to inspect coated pipelines, tanks etc. Complying with standards: ANSI/AWWA C 214-89 ANSI/AWWA C 214-91; AS 3894.1; ASTM D 4787; ASTM G 6; ASTM D 5162; ASTM G 62-B; BS 1344-11; ISO 2746; JIS G-3491; JIS-G 3492; NACE RP 0274; NACE RP 0490-2001; NACE RP 0188-88; DIN 30672; DIN 30670; UNI9736:2006.
