ArcticPRO® LD-2 Dual mode

The LD-2 ArcticPRO® is a dual mode leak detector featuring both electronic sensor and patented UV detection modes. The long life solid electrolyte sensor technology is designed to detect both R-134a and the new HFO refrigerant R-1234yf that is replacing R-134a. The LD-2 is highly sensitive to all HCFC, HFC, blends and HC refrigerants. The LD-2’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 LD-2 runs with standard batteries.
