Electric Spark Leak Detector

The electric spark leak detector applies high voltage through a metal probe brush, generating an electric field on the coating surface. Discharge sparks occur at coating damage points, and defects are located via audible and visual alarms. It is used to detect pinholes and cracks in anti-corrosion coatings on metal substrates, ensuring the protective effectiveness of pipelines and storage tanks.
Selection
When selecting, consider the detection voltage range to cover the coating thickness, ensure handle insulation for safety, and note that the weight of the main unit affects portability. Also, consider environmental adaptability such as explosion-proof ratings, the wear resistance of electrode materials, and the power source type, which determines battery life.
