Tracer Products' Optimax 400, No. TP-8610CS, comes as an economical, cordless, true UV LED leak detection flashlight. It emits less visible light so leaks are clearer and easier to spot, saving valuable inspection time for technicians. Features a high-output UV LED that causes dyes to fluoresce more brilliantly and with greater contrast than with conventional inspection lamps. The flashlight's pre-focused beam optimizes fluorescent response without any adjustments. It works with all proprietary universal/ester and PAG A/C dyes. Features a 10' inspection range. Powered by standard AAA batteries (included) and has 30,000-hour LED service life. Comes with belt holster, lanyard and fluorescence-enhancing glasses.
