Elcometer’s 280 pulsed DC holiday detector is designed to detect holidays in coatings without the need to be grounded to the substrate, making it suited for pipeline and large-surface porosity inspection. It is lightweight at 3 kg (6.6 lb), is fully charged in four hours and can provide as many as 30 hrs of continuous use.

The rugged gage is shockproof and water resistant, and offers a variety of safety features, including a two-stage safety switch; bright LEDs, screen icons and a buzzer signifying when the high voltage is on; and extended ribbing to protect the user from spark creep. Users can either set the test voltage manually or let the internal voltage calculator automatically set the gage to the correct voltage required for the coating thickness value.

Two rechargeable battery packs and a charger, a 5-m (16-ft) trailing earth lead, a rolling spring holder, and a 250-mm (9.8-inch) extension rod also are included with the holiday detector.
