The D440A-UV Refrigerant Gas Leak Detector from RTI features an A/C sniffer and a patented LED UV that emits the optimum wavelength for A/C dye fluorescence. The UV light can be used simultaneously with the heated sensor or independently. It can detect the more current and difficult HFC refrigerants such as R-134a, R-410a, R-407c, R-507, and R-404c, in addition to the new HFO-1234yf and all HCFC (R-22) and CFC (R-12) refrigerants including SNAP approved hydrocarbon blends. The tool's digital leak size indicator takes the guesswork out of whether or not to repair a small leak.
