Main unit, high voltage generator, 2-meter probe wire, grounding wire, probe brush, battery, charger, strap, instrument case, HUATEC calibration certificate, and operation manual.
The instrument applies pulse high voltage to conductive substrates with insulating coatings. When defects like pinholes exist, the air gap is punctured, creating spark discharge that triggers audible and visual alarms for precise defect location.
