High Voltage Spark Leak Detector

High-voltage spark leak detectors generate electric sparks through a high-voltage generator. When the probe approaches coating defects, the electric sparks break down the air, forming visible sparks to detect coating continuity. They are used to detect pinholes and cracks in non-conductive coatings on metal substrates, and are applied in the inspection of anti-corrosion coatings on pipelines and storage tanks.
Selection
When selecting a high-voltage spark leak detector, it is essential to consider that the detection voltage range must match the coating thickness, the output power should be suitable for the working environment, the probe type must conform to the shape of the object being inspected, safety features including overload protection and proper grounding must be ensured, and the device's portability and battery life must meet on-site requirements.
