The DeFelsko HHDKIT PosiTest HHD Kit High Voltage Holiday Detector is a precision instrument that uses pulse DC technology, offering a user-adjustable voltage range from 0.5 to 35kV for detecting holidays, pinholes and other discontinuities in coatings up to 20 mm (780 mils) thick. The PosiTest HHD is ideal for use with a wide range of rolling spring and flat wire brush electrodes.
Voltage calculator feature choose one of 11 international standards, and input the coating thickness to automatically calculate the required test voltage
Strobe light and loud audible alarms emitted when a holiday is detected. Audio alarm mode can be adjusted for differing environments
Removable Smart lithium-ion battery provides power for up to 40 hours of continuous measurement
