Holiday Detector


ISO 29601: Paints and varnishes. Corrosion protection by protective paint systems. Assessment of

porosity in a dry film.

ISO 2746: Vitreous and porcelain enamels. Enamelled articles for service under highly corrosive conditions. High voltage test.The Holiday Detector is a DC voltage Holiday

Detector for detecting pinholes and flaws in insulated coatings on conductive substrates.

Where coatings have to provide an effective safeguard against corrosion, it is essential that any pinholes or flaws that will eventually lead to corrosion are detected at the earliest possible stage, preferably immediately after the coating application.

The test voltage is of high impedance, enabling safe testing, and does not damage or cause burn marks to the coating.

The Holiday Detector is a compact and lightweight instrument, which can easily be carried by the operator with the supplied Neck Strap.

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 Management Cloud (under Calibration) on our website.

All models are supplied in an industrial foam-filled Carrying Case with High Voltage Probe, Band Brush, 10m Earth Cable and Neck Strap.
