LPG/Natural Gas/Coal Gas Leak Detector, Plug-in Sensor Monitor with Audible Alarm and LED Digital Display, for Methane, Propane, Butane Fuel

【Keep Safety】The gas detector is mainly used to detect natural gas (main components: methane), LPG (main components: propane, butane) and urban coal gas (alkane, olefin, arenes). When the combustible gas leakage exceeds the standard, the gas detector will emit a slow, accelerated or hurried, continuous 85dB audible alarm. It cannot detect toxic gases such as carbon monoxide【LED Digital Display & Sound Warning】The gas detector indicator displays 0 under normal conditions. If a flammable gas leak is detected, the numbers 1-9 and A can be displayed on the screen. The alarm will sound and flash red once the concentration is higher than 3% of LEL. The alarm will be in different alarm states according to the concentration of flammable gas【Durability and energy saving】 Standard European plug design, plug and play, no converter required, makes it extremely easy and convenient to install. ABS plastic frame, 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 and hold the lighter switch at the gas inlet of the methane detector, then slowly deflate (do not ignite it during deflation). When the concentration reaches the standard, the alarm will sound until the gas volume in the environment drops below the alarm point. Precautions: The system warm-up time is about 2-3 minutes. During this period, the gas test will not work【Installation Reminder】This gas detector uses high-quality sensors, semiconductor heating and SMT chip technology; do not install it in a place with a lot of dust, oil smoke and water vapor, which may cause false alarms; choose a suitable location to install the alarm according to the actual situationNote: The data are all measured manually, please allow an error of 1-3 cm due to differences in light and display, there may be some color differences, please refer to the actual item received.
