Robinair's No. 16350 Ultraviolet Leak Detection Kit helps you find leaks fast, because you can actually see the leak. You don’t have false triggering or background contamination to contend with, as you do with other types of detectors. The dye combines with the refrigerant lubricant and migrates out at the leak, where it is illuminated in the beam of the UV light. Robinair's UV leak detection dyes won't harm the system and can be used for both automotive and HVAC-R systems. High intensity beam makes even small leaks visible and is bright enough to be used in daylight. Rugged case and a shock-absorbing mounting mechanism protect the lamp during use and storage. UV bulb is rated for 3000 hours and is economical to replace. Comes with a 15' (4.57 m) long cord with battery clips for automotive use or with a transformer for 115V operation, doing away with heavy batteries and the need to recharge. Designed with super luminescence, so leaks are easy to spot, even small ones. Won’t affect the viscosity of refrigerant lubricants and is safe for the entire A/C system. Speeds service, since there’s no need to recover the charge, add dye, and recharge, as with some other brands. Includes: Powerful 50-watt/12-volt UV lamp with 15' cord and battery clips, injection gun with R-134a hose and R-12 adapter, 4 ea. No. 16356 universal A/C dye twist-on cartridges - enough OEM approved and SAE certified dye for 20 applications, UV enhancing glasses, convenient blow-molded storage case, and more.
