The LeakTracker (P/N LT-300) is a powerful, economical UV LED leak detection flashlight that is ideal for all industrial fluid system applications. LeakTracker features a high-output UV LED that delivers superior fluorescent dye response, making industrial leaks easier to spot. It works with all oil- and water-based flurescent dyes, including difficult-to-fluoresce yellow, white and blue dyes — even in dirty fluids. The flashlight features "instant-on" operation. Its compact size allows it to get into cramped areas larger lamps cannot. A rugged, corrosion-resistant, anodized lamp body stands up to years of heavy use. Powered by standard AAA batteries (included), te unit features a 100,000-hour LED service life. LeakTracker comes complete with a lanyard, belt holster, three "AAA" batteries and UV-absorbing glasses.
