Ref: HOLIDAY DETECTOR
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.Operation is by the 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.All models are supplied in a Industrial Foam-Filled Carrying Case with High Voltage Probe, Band Brush, Earth Cable and Neck Strap.

Ref: HOLITECH ACCESSORIES
A range of accesorries to suit the DC Holiday tester from Extension Rods,Broad Brushes,Circular Brushes & Rolling Springs.Broad brush: Brass-filled Brushes for the testing of coatings on large flat areas using the Holitech Holiday Detector. To extend the Broad Brushes for applications where a long reach is required, use with the Extension Rods.Circular: Brass-filled Circular Brushes for the testing of coatings on the internal diameter of pipes.All Brushes come complete with the connector assembly.To extend the Circular Brushes for applications where a long reach is required, use with the Extension RodsRolling Spring: 3/4" phosphor bonze Rolling Spring for the testing of coatings on the external diameter of pipes using the Holitech Holiday Detector.All Rolling Springs require the T01-30268 Rolling Spring Connector Assembly.One assembly can be used on multiple Rolling Springs.The T01-30269 Rolling Spring Pusher Assembly is suitable for larger Rolling Springs, to assist the travel of the spring along the pipe.
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.Supplied in an industrial foam-filled Carrying Case with 150mm Sponge Assembly and 5m Earth Cable.
