Functional characteristics

Leeb710 DC Spark Tester 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 glass lining, fiberglass, epoxy coal tar asphalt, and rubber lining. When there are quality issues with the anti-corrosion coating, such as pinholes, bubbles, and cracks, the instrument will emit a bright electric spark and sound an alarm. Due to the use of nickel hydrogen batteries for power supply (which have the advantages of high capacity, long lifespan, light weight, no pollution, no memory effect, and can be quickly charged and discharged), they are ideal products for outdoor operations. This instrument is designed to be advanced, stable, and can be used in industries such as chemical, petroleum, rubber, enamel, etc. It is a tool for testing the quality of metal anti-corrosion coatings.

operational principle

The electric spark detector is a device that applies a certain amount of pulse high voltage to the surface of the conductive substrate anti-corrosion layer. 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, causing the alarm to sound an alarm, thereby achieving the purpose of detecting the anti-corrosion layer.
