Product Description
Pinhole Detector for detecting pinholes and flaws in coatings on conductive substrates.

These flaws would eventually lead to corrosion and premature failure of the coating.

Supplied in an industrial Carrying Case with Sponge Assembly and Earth Cable (5m).  Calibration Certificate with traceability to UKAS is an optional extra.

Compliant to ISO 29601.

Pinhole Detector
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.
 

Supply
Supplied in an industrial foam-filled Carrying Case with 150mm Sponge Assembly and 5m Earth
Cable. Calibration Certificate with traceability to UKAS is an optional extra.

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.
 

Technical Specification

Operation is by a wet sponge, moistened with water containing a wetting agent, being moved over the coating. If a pinhole is detected, the water will make a conductive path through the pinhole in the coating to the metal substrate, the alarm will sound and the red flashing fault indicator will illuminate.

The Pinhole Detector is suitable for use with coatings up to 500μm.

Voltage accuracy of ±1%.
