Wet Sponge Pinhole Detector
for Thin Film Porosity Testing

Compact DC Porosity Detector

Uses the wet sponge method to detect pinholes in coatings.

Models available: 9, 67,5 and 90 volt Selectable and 67.5 volt fixed.

Large sponge head & telescopic handle which extends to 47" (1.2m).

We highly recommend high voltage holiday and porosity testing in lieu of wet sponge testing when working with coatings over 150µm, or coatings in corrosive environments.

Complies with the requirements of AS3894.2-2002 (Wet Sponge Testing); ASTM G62-A; NACE RP0274-98; ASTM G6 and AS1580.485.1. CE Compliant.
