Imperial LD-900 Refrigerant Gas Leak Detector

Imperial leak detectors feature long-life heated sensor technology, designed for high sensitivity. The 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. All models use standard alkaline batteries- rechargeable batteries are not required.

Detects all HCFC, HFC, HFO, blends and HC refrigerants, including R-134a and the new HFO refrigerant R-1234yf that is replacing R-134a. Includes (4) AA batteries and sensor maintenance kit.
