DC Spark Leak Detector leak detector digital DC spark leak detector coating quality testing

MTH-7D digital DC spark leak detector,based on the principle of high pressure pulse conducting through anti-corrosion layer,can quickly detect the crack leakage of the coating. While using, if there is pinhole,bubble and crackle in the layer ,the instrument will make a bright spark and accompanied by a warning tone.The operation is extremely simple,and It’s powered by the unique design relies on the large capacity battery packs that no longer rely on 220V power supply.It is suitable for engineering site operations. The performance of the product is stable and reliable, thus widely used in Oil and Gas pipelines,Cable,Enamel,Metal Casting Pipe,Hull and other metal surface corrosion insulation construction quality and aging corrosion monitoring,it is also the necessary testing equipment in chemical, oil, rubber industry.
