Tracer Products manufactures a variety of technologically-advanced, budget-friendly, efficient, easy-to-use fluorescent leak detection kits. The Tracerline OPTI-PRO EZ-Shot AC Kit makes it easy for technicians to find all air conditioning leaks quickly and easily. At the heart of the A/C kit is the OPTI-PRO, a cordless, “true UV” (violet light) LED leak detection flashlight that provides optimal fluorescent dye response and contrast so leaks glow brilliantly. It works with all Tracerline universal/ester and PAG A/C dyes. The flashlight has power comparable to high-intensity 100-watt lamps, with an inspection range of 15 feet (4.6 m) or more. Powered by 3 AAA batteries (included), it has a 100,000-hour LED service life.
