Porosity

The DC Holiday Detector use precision high voltage technology to detect 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.

Supplied in an industrial Carrying Case with High Voltage Handle, Band Brush Probe, 10m Earth Cable and Neck Strap. Calibration Certificate is an optional extra.

Brass-filled Brushes for the testing of coatings on large flat areas using the DC Holiday Detector.

Brass-filled Circular Brushes for the testing of coatings on the internal diameter of pipes using the DC Holiday Detector.

All Brushes come complete with the connector assembly.

Phosphor bonze Rolling Spring for the testing of coatings on the external diameter of pipes using the DC Holiday Detector.

All Rolling Springs require the SA490 Rolling Spring Connector Assembly.
One assembly can be used on multiple Rolling Springs.

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.

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