The Spectroline OLK-400BEZ/E complete BigEZ leak detection kit contains everything needed to locate refrigerant leaks in medium- to large-size AC&R systems — including high-pressure R-410A systems. The exact source of every leak will be revealed by the kit’s bright fluorescent glow. At the heart of the kit is the OPTI-LUX 400, a powerful rechargeable violet-light LED leak detection flashlight. It emits less visible light compared to standard blue-light inspection lamps, thus all AC&R leaks are easier to locate. The OPTI-LUX 400 has power comparable to high-intensity 150-watt lamps and has an inspection range of 25’ or more. Also included are a BigEZ dye injector, a multi-dose 4-oz. universal/POE dye cartridge, a hose assembly with check valve and low-loss fitting, a purge fitting, an 8-oz. spray bottle of GLO-AWAY dye cleaner, three drip plugs, an AC/DC charger and fluorescence-enhancing glasses.
