AC&DC Knob Type Intelligent Frequency Conversion High Voltage Holiday Detector Pin Hole Detector
General introduction
HUATEC HD-106A/B/C series AC&DC 110-230V knob type intelligent frequency conversion electric spark pinhole detector uses intelligent frequency conversion high voltage detection technology, widely used to detect pinholes, cracks and other damage and defects in non-conductive coating on conductive substrate (such as metal), it detects the quality of insulating and anticorrosive coating on the surface of storage tanks, valves and pipelines. Portable size, rugged ABS shell, the instrument appearance design is beautiful, stable and reliable performance, can be widely used in anticorrosive engineering, plastic airtight joint detection, concrete coating layer air tightness test, petrochemical pipeline corrosion inspection, enamel production industries, is used to detect an essential tool for metal surface insulating anticorrosive coating quality.

Working principle
Holiday detector is based on a variety of conductive insulating coating on substrate surface to add a certain amount of pulse pressure, such as anti-corrosion layer, thin metal or pinhole of leak leakage, when pulse high voltage, air gap will be punctured and produce spark discharge, at the same time send pulse signal to alarm circuit, the alarm sound and light alarm, so as to achieve the aim of the anticorrosive layer of quality testing.
