Portable holiday detectors are designed for various pipeline, plant, and other surface applications where the inspection surface remains stationary and the detector is moved over the inspection surface. High voltage detectors are used for thicker surface coatings, such as those used on pipelines and other industrial applications. low voltage, wet sponge detectors are used for thin film applications.
High Voltage DC
Durable, Reliable and Dependable, for decades the SPY® DC Holiday Detector was built to handle the most EXTREME environments!
High Voltage Pulse
For thicker coatings such as coal tars, extruded and tape coatings, the Model 785 has a range of infinite voltage settings from 1,000 to 15,000 volts. This wide range permits you to maintain a steady inspection rate on most types of coatings on most pipe sizes without changing detectors. Pulse voltage output only.
Low Voltage detector operates on a single 9-volt alkaline battery. Unit output voltage is 67.5 volts DC. This voltage makes the detector highly sensitive and accurate. Compact and light weight with no bulky battery packs allowing for non- destructive inspection of paints, epoxy paints and coatings 1-20 Mils.
Inspect large surfaces faster and with less operator fatigue using a quick attach, easy to use roller sponge electrode (Optional Accessory).
