The PosiTest HHD C High voltage Holiday Detector is a Continuous DC Holiday Detector designed to locate defects and discontinuities (called “pinholes” or “holidays”) in a coating system applied to a conductive substrate. High voltage holiday detectors are commonly used to inspect non-conductive coatings thicker than 500 µm (20 mils). Designed for maximum utility, the powerful Li-on batteries of the PosiTest HHD C fit neatly within the wand handle eliminating the need for a separate battery box - reducing weight and eliminating operator fatigue.
