The PCWI Wet Sponge Porosity Detector is designed to non-destructively detect pinholes in coatings up to 500um using the "wet sponge method". A voltage from the battery supply is transmitted through the probe and dampened sponge attached. Because the instrument's earth is connected to the substrate, when a flaw is encountered, the conductive path is made and the alarm sounds.
The unit features three test voltage options; 9V for coatings up to 300um, 67.5V for coating assessment to ASTM standards, and 90V for coatings up to 500um.
Kit includes: Unit and Handle including Sponge, belt/pocket clip, seven metre earth lead and clip, carry case, instruction manual with calibration certificate.
Complies with the requirements of:
AS3894.1-2002 (Wet Sponge Testing); ASTM G62-07; ASTM G60-07; ASTM D5162-08; Nace Standards: RP0274-2004 & SP0188-2006
