The Tinker-Rasor low voltage holiday detector verifies a pinhole-free coating using the low voltage wet sponge holiday detector. Tinker-Rasor is a leader in holiday detection equipment. The portable, plastic solid state transitorized nondestructive low voltage (67.5v) detector uses regular potable water from a wetted sponge and a ground wire (attached to the uncoated substrate) to complete a circuit and produce an audible signal indicating a pinhole or flaw in the coating. A red indicator light also illuminates when the detector alarms. The tester is suitable for use on any nonconductive coating (up to 20 mils thick) applied to a conductive substrate. While there is no spark hazard during detection, the device operates on batteries and is not intrinsically safe.
