HD-108A/B/C Series AC/DC Intelligent Frequency Conversion Electric
Spark Pinhole Holiday Detector
Summary:
HD-108A/B/C series 110/230V AC/DC intelligent frequency conversion
electric spark pinhole holiday detector uses intelligent frequency
conversion high voltage detection technology, used to detect
pinholes, cracks and other damage and defects in non-conductive
coating on conductive substrate (such as metal), can be used to
detect the quality of insulating and anticorrosive coating on the
surface of storage tanks, valves and pipelines. Host for portable,
rugged ABS shell, the instrument appearance design is advanced,
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.

Detection principle:
Spark 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.
