Function
D1 Porosity Holiday detector is a special testing equipment used to detect oil and gas pipelines, cables, enamel, metal tank, hull and other protective coatings flaws. It is a simple and practical equipment.
Characteristic
1.Low power consumption, small size, light weight;
2.Simple operation;
Accessories
Charger, high pressure gloves, long cable, short connecting line, Connecting magnet, earth rod, The brush plate, Manual
Principle
The detector generates a high DC voltage that is applied to the coating surface through a probe. The detector is connected to the substrate via the high voltage returned. When the probe is passed over a coating flaw, then the electrical circuit is completed and current flows from the probe to the substrate. As a result, audible and visual alarms are activated in the detector and a spark may be produced at the flaw.
