Yellow Jacket, 69337, AccuProbe UV Handheld Leak Detector with US, EU, UK, AU and NZ plugUse the electrolyte sensor or UV technology (or both at the same time) to detect 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 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. Our 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.The AccuProbe UV is equipped with the advanced digital SmartAlarm LED display. This feature takes the guesswork out of whether or not to repair a small leak. Unlike the more traditional LED bar graphs that copy or mimic the audio alarm signal, the SmartAlarm digital leak size indicator measures, registers and displays the leak size independently from both the audio alarm and sensitivity level on a scale of one to nine:1 to 3 - less than 0.1 oz./yr.4 to 6 - 0.1 to 0.5 oz./yr.7 to 9 - more than 0.5 oz./yr.Features:Improved, robust, ergonomic design is easy to use in close areas and extendable into hard - to - reach areasLong life, stable sensorInstantaneous response timeClears in 12 seconds or less after exposure to a 1.75 oz (50 g)/year leakAutomatic calibration and reset to environmentLow battery indicatorMicrocontroller technologySAE J2791 Certified, CE Marked, EN 1462424 - month limited warrantyMade in the USA.
