Pinhole spark leak Detector

The pinhole spark leak detector moves a high-voltage probe over the coating surface. When encountering pinhole defects, the current breaks down the air, generating an electric spark that indicates the location of the leak. It is used to detect continuity defects in non-conductive coatings on metal substrates, such as anti-corrosion layers on pipelines and storage tanks, ensuring the coatings are free of pores.
Selection
When selecting, consider matching the detection voltage range to the coating thickness, ensuring the probe type suits the workpiece shape, and that the equipment includes safety protection and sensitivity adjustment. Focus on ease of operation, environmental adaptability, and maintenance costs to ensure it meets on-site detection requirements.
