DC Spark Leak Detector

The DC spark leak detector generates electric sparks on the coating surface through high-voltage direct current to detect defects such as pinholes and cracks in insulating coatings. When the probe scans over a damaged area, the electric spark breaks down the air to form a conductive path, triggering audible and visual alarms. It is used for on-site inspection of anti-corrosion coatings on pipelines and storage tanks to ensure coating integrity.
Selection
When selecting a DC spark leak detector, it is essential to consider the matching of the detection voltage range with the coating thickness, ensuring that the output high voltage is stable and adjustable. The probe type should be suitable for different surface shapes, and the alarm sensitivity must be reliable. The power source type should meet on-site requirements, while the instrument’s weight and protection level affect its portability and durability.
