Non Destructive Testing Equipment Wet Sponge Pinhole Porosity Holiday Detectors HD-104 Spark Detector


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.

Our Porosity Holiday Detector HD170 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.
