Yellow Jacket 69337 AccuProbe UV detects HFC, HCFC and HFO refrigerants, including SNAP approved hydrocarbon blends. The Smart Alarm LED shows how big or small a leak is on a scale of one to nine. With the electrolyte sensor, UV lights and Smart Alarm indicator, this is the only tool you need for fast, easy and certain leak detection.

The ultra-sensitive sensor of the Yellow Jacket 69337 AccuProbe UV Handheld Leak Detector allows it to detect even the most difficult to detect R-134a, R-404A, R-407C, R-410A and 1234yf refrigerants. The exclusive solid electrolyte sensor technology reduces heat and gives the sensor longer life than traditional heated anode or heated diode detectors.

The AccuProbe UV features low, normal and high sensitivity levels with visual and audible signals, and a 3 LED UV light system that works with 395-415nm wavelength leak tracing dyes. The audible alert, which can also be muted, and the flashing visual alarm indicator at the probe end increase in frequency and duration as concentration increases.
