Keep Safe-- The gas detector is mainly used to detect natural gas (main components: methane), LPG (main components: propane, butane) and urban coal gas (alkane, olefin, arenas). When the combustible gas leak exceeds the standard, the gas detector will sound a slow, accelerated or hurried, continuous 85dB sound alarm. It cannot detect poisonous gases such as carbon monoxide. Durability and Energy Saving-- The standard European plug design, plug-and-play, no converter required, the makes it extremely easy and convenient to install. This detector is anti-mold, anti-pest and anti-corrosion. Flame retardant ABS plastic, easy to clean. Uses less than 2 watts of electricity, significant energy saving. Widely used for restaurant, kitchen, hospital, hotel, oil factory, garage, gas station and so on. Test Method-- Press the switch of the lighter located at the gas inlet of the methane detector and hold it down, then deflate slowly (do not turn it on during deflation). When the concentration reaches the standard, the alarm will sound until the volume of the gas in the environment falls below the alarm point. Precautions: System warm-up time is approximately 2-3 minutes. During this period, the gas test will not work.
