Techno Tools’ D440A features a long life heated sensor technology that is designed to detect the more current and difficult HFC refrigerants such as R-134a in addition to all HCFC and CFC refrigerants including hydrocarbon “blends”. The D440A’s unique digital leak size indicator takes the guesswork out of whether or not to repair a small leak. The digital display is independent from the audio alarm and sensitivity level, allowing the precise pinpointing of the leak source. The D440A does not require rechargeable batteries.
