Low-frequency pulse type, microcurrent type
A high voltage of 5 to 25 kV is applied to short-circuit the coating defect area, generating a spark for detection. It comes with a buzzer and lamp, and the target coating thickness is 1 mm or more. Due to its low-frequency pulse type and microcurrent design, it can perform high voltage pinhole inspection without damaging the coating.

It can detect pinholes in metal coatings. (Target coating thickness of 1mm or more, detection voltage of 5 to 23kV)
■The goal is to detect defects in the coating and lining films for rust and corrosion prevention without damaging the films. ■Measurements are taken at low frequency to avoid high frequencies that are prone to thermal destruction. ■Achieving a compact portable design by reducing power consumption and enabling battery operation. ■Considering the degradation of the coating, a high-voltage pulse method is adopted to relatively minimize the application time of high voltage. ■To avoid impacts on the human body and damage to the coating, the discharge current is suppressed. ■The structure allows for confirmation of the voltage applied to the coating and voltage adjustment.
