Detection method: Needle hole detectors usually use non-destructive testing methods, without the need to damage or change the appearance and structure of the tested object. It can detect objects of different shapes such as planes, surfaces, and pipelines online or offline.
Detection principle: The pinhole detector uses high-voltage arc discharge or similar technology to generate high-voltage discharge Electrical breakdown effect. When there are pinholes or cracks on the surface of the detection object, the arc will form discharge channels through these defects, thereby generating observable signals.
