Portable natural gas and propane leak detector with audible and visual alarm, detects 12 types of gas, AAA battery not included

【Combustible Gas Leak Detector】 Gas Leak Detector suitable for LPG, methane, ethane, propane, butane, natural gas, coal gas, combustible gas, LNG, etc., will identify a leak with Accuracy, reducing the risk of gas leaks and ensuring the safety of your family and property.
【Visual and Audible Gas Alarm】 The gas detector uses both a visual and an audible alarm, with a detection time as fast as 0.5 seconds. When the bar graph increases and the detector beeps, you know that gas has been detected. The alarm increases with the amount of gas, and the LCD screen turns red when the gas concentration is high.
【Easy to Use】 Powered by 2 AAA alkaline batteries (not included). When the battery voltage drops below 2.4V, the power indicator flashes to remind you to replace the batteries. The detector automatically shuts off after 5 minutes of inactivity without operation or gas detection. Detection range: 50 to 1,000 ppm* (*based on methane)
【Compact Design】 Pocket-sized with a pen loop so you can carry it in your shirt pocket. The textured, non-slip material makes it easy to grip. With the included storage bag, the natural gas detector is also easy to store.
