The OPK-341 industrial leak detection kit from Spectronics offers a solution to pinpoint the source of fluid leaks in hydraulic equipment, compressors, engines, gearboxes, fuel, and other synthetic and petroleum-based industrial systems. The kit features an Optimax 3000 cordless, rechargeable, blue-light LED inspection flashlight that is brighter than regular LED flashlights and offers an inspection range up to 20 ft (6.1 m). Powered by a rechargeable NiMH battery, the flashlight has an LED life of 50,000 hours. Also included are two bottles of Spectronics' Oil-Glo 44 concentrated fluorescent oil dye, compatible with all synthetic and petroleum-based fluids. When a leaking industrial system is scanned with the Optimax 3000 flashlight, the dye glows to reveal the location of the leak. Dye cleaner, ac and dc chargers, and fluorescence-enhancing glasses are also included, all packaged in a rugged carrying case.
