## Features

- 【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, arenas). When the combustible gas leak exceeds the standard, the gas detector will emit a slow or accelerated or hurry, continuous 85DB sound alarm. It cannot detect toxic gases such as carbon monoxide
- 【LED digital display and audible warning】-- The gas detector indicator displays 0 in normal conditions. If a flammable gas leak is detected, the numbers 1-9 and A can be showed on the screen. Alarm sounds and flashes red once the concentration above 3% LEL. The alarm will be in different alarm states based on the concentration of flammable gas
- 【Durability and energy saving】-- Standard British specification plug design, plug-and-play, no converter required, makes it extremely easy and practical to install. Fireproof ABS plastic, easy to clean. Uses <2 watts 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 and deflate slowly (do not turn on the lighter during deflation). When the concentration reaches the standard, it will alarm, until the volume of the environmental gas falls below the alarm point. Precautions: The system warm-up time is about 2-3 minutes. During this period, the gas test will not work
- 【Remind for Installation】-- This gas alarm 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 situation
