Detection principle and method

Leak detection principle: the insulation corrosion layer on the metal surface is too thin, the resistance value and the air gap density are very small, when there is a high voltage after the formation of air gap breakdown and spark discharge, to the alarm circuit to generate a pulse signal, alarm alarm sound and light alarm, according to this principle to achieve the purpose of corrosion detection layer.
