Pinhole Detector TRC-250B Rental
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.
basic information
Product Code: 20506 *Please provide this number when making inquiries for a smoother process. Pinholes significantly reduce the rust and corrosion prevention effects of paint and lining films. The pinhole detector (for thin materials) captures such pinholes with a microscopic view, preventing resource and energy loss caused by pollution, contamination, and corrosion before it occurs.
