The Yellow Jacket 69373 Combustible gas leak detector detects all hydrocarbon and other combustible gases including propane, methane (natural gas) butane. It's state of the art sensor utilizes the latest technology to achieve superior sensitivity with instantaneous response time, yet rugged enough to withstand years of use even in the toughest environments. The sensor's low power consumption allows for long battery life using standard AA alkaline batteries.

The 69373's advanced electronic circuitry is entirely automatic, requiring no manual adjustments and features multiple sensitivity levels and audio and visual display to indicate the leak strength. Its sleek ergonomic design includes a long flexible probe easy to use in both close and hard to reach areas.

The unit is preset at normal sensitivity, but can be switched to high or low. Slow beeping indicates that unit is warmed up. Frequency increases when a leak is detected until an alarm sounds when moving into high gas concentration. The SmartAlarm LED indicates leak size. If no leak is detected in a suspected area, selecting high sensitivity will detect even low levels in the area. Move the tip over more defined areas, and you will be alerted when the tip encounters the concentration at the leak source.

The 69373 is designed to make leak detection fast and reliable in a wide range of applications including residential and commercial combustion appliances, gas lines and pipes, heat exchangers and numerous other applications.
