海綿針孔儀 Holiday Tester

Holiday Detector

The Pintech is a multi-voltage Pinhole Detector that 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.

Optional Calibration Certificates are available with traceability to UKAS.
