Electric Spark Pinhole Detector

The electric spark pinhole detector generates an electric field on the coating surface through a high-voltage probe. When pinhole defects are present in the coating, the electric field breaks down, producing visible sparks. It is used to detect the continuity of anti-corrosion coatings on metal substrates, enabling rapid localization of coating damage points in on-site anti-corrosion projects such as pipelines and storage tanks.
Selection
When selecting, consider the detection voltage range to cover the coating thickness, ensure the probe shape matches the workpiece curvature, and verify that it has audible and visual alarm functions. DC types are suitable for outdoor environments without power sources, while AC types are ideal for factory settings. The protection rating must meet the on-site working conditions, and the electrode material should be wear-resistant.
