Yellow Jacket 69354 AccuProbe™ II Leak Detector

Detect all HCFC refrigerants such as R-22 and R-124

The ultra-sensitive long life sensor with exclusive Heated Electrochemical Sensor Technology (HES) also detects the more current, difficult-to-detect HFC refrigerants such as R-134a, R-404A, R-407C and R-410A.

When finding leaks, it is important to note that the AccuProbe responds to changes in concentration of refrigerant. For this reason, the detector will stop alarming even though it is held at or near the source of the leak and will not alarm again until the detector senses a change in concentration. To verify the exact location of the source of the leak, always move the probe away from the area of the leak briefly to allow the sensor to reset at a lower concentration, and then bring it back again until the exact location of the leak source has been verified.
