SL-Ⅲ A, B-type spark leak detector metal surface insulation coating is too thin, leakage iron and leakage at the micro-hole resistance and air gap density is very small, when there is high pressure through the formation of air gap breakdown and spark Discharge, to the alarm circuit to produce a pulse signal, the alarm sound and light alarm, according to this principle to achieve the purpose of anti-corrosion layer leak detection. SL-Ⅲ series spark leak detector is used to detect oil and gas pipelines, cables, enamel, metal storage Tank, hull and other metal surface coating construction quality and aging corrosion point of the micro-hole, a special air-gap testing equipment. The instrument meets the national standard GB7993 and the German standard D2N51163.

▲ low power consumption, small size, light weight
▲ Simple, intuitive and convenient features
▲ The pointer meter indicates the output voltage and supply voltage.
