Portable Pinhole Detection Meter

The portable pinhole detector generates an electric field on the coating surface through a high-voltage probe. When encountering a pinhole, the current breaks down the air to form a circuit, triggering audible and visual alarms. It is used for on-site detection of through-thickness defects in anti-corrosion coatings on metal substrates, plastic films, and other materials to prevent media leakage.
Selection
When selecting, pay attention to the detection voltage range to match the coating thickness. The DC type is suitable for wet film detection, while the AC type can measure dry films. The aluminum probe is corrosion-resistant and equipped with a ground wire to ensure safety. Choose single-pole or dual-pole mode based on the material's conductivity, with a lightweight design for easy handheld operation.
