Portable Propane Methane and Natural Gas Leak Detector (Batteries Included), Combustible Gas detector has Sound Light and vibration Alarm Function. OT131 gas detector is a pump-suction ultra-high sensitivity gas leakage detector. Electrochemistry sensor is more suitable for locating and detecting leakage gas. It is compact, easy to operate, easy to carry, and can also be attached with a flexible probe, comfortable handle. It also can show a unique concentration curve.
