The Holiday Detector is a DC Holiday Tester that tests and detects 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.
Operation is by a test voltage being applied to the coating by moving a brush electrode across the surface and where there is either a pinhole or flaw, the voltage will spark through the coating, a red indicator will flash and an audible alarm will sound. The detected flaw can be marked for subsequent repair, and testing resumed for the remaining surface area.
The Holiday Detector is a compact and lightweight instrument, which can easily be carried by the operator with the supplied Neck Strap.
The test voltage is of high impedance, allowing for safe testing, and does not damage or cause burn marks to the coating.
Calibration Certificate with traceability to UKAS is an optional extra.
Coatings on concrete as well as steel and iron substrates can be tested.
All models are supplied in a Industrial Foam-Filled Carrying Case with High Voltage Probe, Band Brush, Earth Cable and Neck Strap.
