✔ Reliable Gas Leak Detector: Y201 is only designed for combustible gas detection and can accurately locate methane, natural gas, propane, butane, ethane, coal gas, gas oil, gasoline, sewer gas, alcohol, and other combustible gas leaks. It only takes 10s to warm-up and start working.
✔ Flexible Probe for Easy Detection: The portable gas detector has a 12-inch flexible probe that can be bent to detect gas leaks in narrow and hard-to-reach areas like basements, ship holds, natural gas pipelines, RVs, and sewers.
✔ Easy-to-Use Design: Y201 has only two buttons (on/off switch and sensitivity dial), making it very easy to use. Powered by 3 AAA batteries (not included), it can be carried around and used indoors, outdoors, camping, or RVing.
