Kedian DJ-6-A EDM leak Detector detection thickness: 0.03~1mm (or customized according to customer requirements), output high Voltage: 600V~8000V, EDM Detector is a special instrument used to detect the quality of metal anti-corrosion coatings, the use of this EDM Detector instrument can be used for different thickness of glass-lined, FRP, epoxy coal asphalt and rubber lining and other coatings, quality testing. When there is a quality problem with the anti-corrosion layer, such as pinholes, bubbles, cracks and cracks, the instrument will emit a bright electric spark and an audible alarm at the same time. Since the EDM Detector is battery-powered, it is particularly suitable for field operations. The EDM Detector instrument design is professional, stable and reliable, the EDM Detector can be widely used in the chemical, petroleum, rubber, enamel industries, is used to detect the quality of metal anti-corrosion coating required tools.
The EDM Detector is by adding a certain amount of pulse high pressure to the surface of the anti-corrosion layer of various conductive substrates, such as because the anti-corrosion layer is too thin, leaking metal or there is a leaking pinhole, when the pulse high Voltage passes, it will form an air gap breakdown and produce spark discharge, and at the same time send a pulse signal to the alarm circuit, so that the alarm will send out a sound alarm, so as to achieve the purpose of detecting the anti-corrosion layer.
