Electronic and auto MTH-7D digital DC spark leak detector testing equipment
Overview
MTH-7D digital DC spark leak detector,based on the pulse of high pressure conduction through the principle of anti-corrosion layer,can quickly detect the crack leakage of the coating. Using,in view of the quality of the coating,in case of the pinhole,bubble and crackle ,the instrument will make a bright spark,accompanied by a warning tone,the operation is extremely simple,It’s powered by the unique design relies on the large capacity battery packs,can get rid of 220V power supply,applicable to 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 the necessary testing equipment in chemical, oil, rubber industry.
Product features
- Applicable to different thickness of the glass lining, glass steel, epoxy coal tar pitch and rubber lining and other coating quality testing；
- Battery powered,applicable to field engineering site operation；
- LCD display,can directly display the output of high pressure(KV)；
- The output voltage of the pulse voltage can be adjusted directly by turning the knob,easy and convenient to meet the needs of different anti-corrosion testing；
- Two different probes applied to different detection environment；
- Low power consumption,small volume,light weight,simple operation,easy to use.
Working principle
A certain pulse voltage is applied by applying a Anti-corrosive coating to the conductor, if the coating is too thin or there is some metal leakage body,leaky pinhole,pulse high voltage, it will break through the air gap to discharge spark,at the same time ,the alarm will receive the pulse signal,and send out sound and light alarm,and then achieve the purpose of coating detection.
