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.
Applications
1,oil and gas Anticorrosive factory, pipelining company,
construction departments and qualitative inspect branch.
2,also use to gas company and water company pipeline inspecting
3,Shipbuilding, petrochemical plant, factory, machinery plant,
enamel factory and bridge engineering anticorrosion-layer
inspecting.
4,Pipeline transportation company anticorrosion-layer inspecting

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.
