The Pintech Pinhole Tester is multi-voltage (9V, 67.5V, 90V) and uses the wet sponge principle to detect through-pinholes, cracks and damaged areas on non-conductive coatings on conductive substrates. These flaws would eventually lead to corrosion and premature failure of the coating.
Operation is by a wet sponge moistened with a wetting agent, being moved over the coating. The wetting agent penetrates any pinhole and makes a conductive path through to the substrate. The Pintech detects this conductive path and indicates that a pinhole has been detected by sounding an audible alarm and giving a visual warning by a red flashing indicator. The flaw can now be marked for repair and further testing can be resumed.
The Pintech has test voltages of 9 Volts, 67.5 Volts and 90 Volts, which are easily selectable.
Complies With International Standards: BS EN ISO 8289 A, BS 7793-2, ASTM D-5162, ASTM G62-87, ASTM G6-83 and NACE RP 0188.
