Pinhole Detector Unit

Pinhole detectors apply an electric field or light beam to the coating surface based on the principles of high-voltage discharge or photoelectric detection. When pinhole defects exist, the current or light signal exhibits abnormal changes, allowing the localization of tiny penetrating pores. They are used to detect the integrity of materials such as metal anti-corrosion coatings and plastic films, preventing medium leakage.
Selection
When selecting, consider the material's conductivity to decide between high-voltage spark or low-voltage wet sponge types; match the detection voltage range according to the coating thickness; on-site environments require explosion-proof ratings or portable designs; it is necessary to verify the detection sensitivity's compliance with standard specifications.
