The LD-2 features two detection modes, a solid electrolyte gas sensor, and a patented UV dye detection system. It has a long life solid electrolyte sensor technology that is designed to detect the more difficult HFC refrigerants such as R134a and the new HFO refrigerant R1234yf. The instrument's unique digital leak size indicator takes the guesswork out of determining leak size. The digital display is independent from the audio alarm and sensitivity level, allowing the precise pinpointing of the leak source.
