Holiday Detector

DGT-HD6

DGT-HD6 holiday detector is intelligence pulsed high voltage protecting coating quality detector. It install anti-jamming intelligent chip, anti-jamming LED screen and brand new digital control circuit to make a accurately high voltage output ± （ 0.1KV+3%reading ） .It can adjust its value of voltage according to the thickness of protecting coating. DGT-HD6 use lithium battery for power source, it is also can be used in field.

When high voltage probe brushed pass non conductive coating, If the coating is too thin or metal has leakage or pinhole, the air gap will be punctured and produce spark discharge when pulse high voltage. At same time, detector will record leak number.
