State of the art technology assuring precise, unambiguous readings, makes leak finding across a wide variety of refrigerants easy and quick. It precisely pinpoints a place of the leaks of the refrigerant in air-conditioning systems. The sensor detects halogenated refrigerants such as R-134a, R-404A, R-407C, R-410A, R-22, Freon, etc. A suction pump provides instant response and quick sensor clearing, which speeds up the leak detection process. Cutting edge accuracy with microprocessor controlled semiconductor gas sensor and advanced digital signal processing. It has clear leak indication with audio and tri-color visual LED display with High-Medium-Low leak sensitivity selector and a 15.5” (40 CM) flexible stainless probe. Operates on 2C size alkaline batteries, which provides approximately 16 hours of power under normal usage.
