The Pinhole Detector 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 Pinhole Detector 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 Pinhole Detector has test voltages of 9 Volts, 67.5 Volts and 90 Volts, which are easily selectable.

The Calibration Certificate with traceability to UKAS is an optional extra.
The Certificate is supplied as hard copy and is available online through the Calibration Portal (under Browse Categories) on our website.
The Calibration Portal lists all your equipment calibrated by Paint Test Equipment, showing the renewal dates and enabling Calibration Certificates to be viewed at any time.

Supplied in an industrial foam-filled Carrying Case with 150mm Sponge Assembly and 5m Earth Cable.
