The OLK-400BEZ/E Complete BigEZ™ Leak Detection Kit contains everything needed to locate refrigerant leaks in medium to large a/c and refrigeration systems, including high-pressure R-410A systems. The exact source of every leak will be revealed by its bright fluorescent glow. At the heart of the kit is the OPTI-LUX™ 400, a rechargeable violet light LED leak-detection flashlight. The OPTI-LUX 400 has power comparable to high-intensity 150-W lamps. It has an inspection range of 25 feet (7.6 meters) or more. Also included in the kit are the BigEZ™ dye injector, a multi-dose universal/polyolester (POE) dye cartridge, a hose assembly with check valve and low-loss fitting, a purge fitting, a spray bottle of GLO-AWAY™ dye cleaner, three drip plugs, a charger, and fluorescence-enhancing glasses. All components are packed in a rugged carrying case.
