NM01HHDKIT
The DeFelsko PosiTest® HHD High Voltage Holiday Detector is a rugged, reliable, and versatile instrument used to detect discontinuities (holidays) such as pinholes, cracks, and bare spots in protective coatings applied to conductive substrates. This essential tool ensures the long-term performance and corrosion resistance of various coatings.
The PosiTest® HHD offers a wide output voltage range of 0.5 to 35 kV, allowing it to test coatings with a thickness of up to 20 mm (780 mils), based on recommendations outlined in NACE SP0274-2011. This broad range makes it suitable for a multitude of coating types and thicknesses across diverse industries.
This detector features a lightweight and ergonomic design for comfortable extended use in the field. It offers both DC (continuous) and pulsed DC voltage modes, providing flexibility for different coating materials and testing requirements. The PosiTest® HHD is designed with safety in mind, incorporating features such as a safety switch and a ground fault indicator.
The instrument is compatible with a wide selection of interchangeable electrodes (wands and rolling electrodes) to accommodate various shapes and sizes of test pieces. It provides both audible and visual alarms to clearly indicate the detection of a holiday.
