one、DC spark detector for leak detection of anti-corrosion coatingAO-2 Product Introduction:

DC spark detector for leak detection of anti-corrosion coatingIt is an instrument used to detect the quality of metal anti-corrosion coatings. This instrument can be used to perform quality testing on coatings of different thicknesses, such as enamel glass, fiberglass, epoxy coal tar, and rubber lining. When there are quality issues with the anti-corrosion coating, such as pinholes, bubbles, and cracks, the instrument will emit bright electric sparks and sound an alarm. Due to its use of nickel hydrogen batteries for power supply (which have the advantages of high capacity, light weight, no pollution, no memory effect, and can be quickly charged and discharged, making it an ideal green and environmentally friendly product), it is particularly suitable for field operations. This instrument is designed to be advanced, stable and reliable, and can be widely used in industries such as chemical, petroleum, rubber, enamel, etc. It is a tool for detecting the quality of metal anti-corrosion coatings.
Detection principle:
The direct current spark detection instrument applies a certain amount of pulse high voltage to the surface of various conductive substrate anti-corrosion layers. If the anti-corrosion layer is too thin, leaks metal or has gas leakage pinholes, when the pulse high voltage passes through, it forms an air gap breakdown and generates spark discharge. At the same time, it sends a pulse signal to the alarm circuit to make the alarm sound an alarm, thus achieving the purpose of detecting the anti-corrosion layer.
