Bosch LD 020 – Air conditioning leak detector


BOSCH LD 020 – Air Conditioning Leak Detector

The LD 020 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. The LD 020 is highly sensitive to all HCFC, HFC, blends, and HC refrigerants. The digital display is independent from the audio alarm and sensitivity level, allowing the precise pinpointing of the leak source. The LD 020 does not require rechargeable batteries.
