LD-2 Dual Mode Refrigerant Gas Leak Detector

Item Number: RTI0268063500    Supplier: MAHLE AFTERMARKET INC SERVICE SOLUT


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 R-134a and the new HFO refrigerant R-1234yf. 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.
