## Description

Product Description D MODUN Gas Detector

Review: A nice simple safety device - After realizing that my current battery-powered natural gas detector was broken (it even beeped outside!) I decided to try a plug-in. This product is really simple, just take out of the box and plugin. It takes a minute or two to set up but soon after the clear display was '0' telling me I was safe. Nice and reassuring. The instruction booklet states that the gas will collect around the ceiling, the detector is to be placed 30cm below and 1.5 m from the air (a window). This means it might be hard to find a suitable place if you have a really small room. For myself, I probably need to move mine further from the window but I still feel that this product has helped alleviate my worries about natural gas.
Review: Saved our lives - Yes, very good. Detected a gas leak in the house within 20 minutes and subsequently called the National gas line and my gas was immediately turned off pending repairs. Life saver!

## 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

Yes, very good. Detected a gas leak in the house within 20 minutes and subsequently called the National gas line and my gas was immediately turned off pending repairs. Life saver!

### ⭐⭐⭐⭐⭐ Saved my mum’s life
*by C***V on 2 September 2024*

I bought this for my mum’s new holiday caravan as a new boiler had been installed just before she bought the caravan. Four days after she moved in, the gas alarm went off at 3am. Thankfully it woke her up. The fire brigade said she would have been dead had she not bought the alarm. It was reading a gas level of 4 and climbing due to a boiler installation issue. I can’t rate this product enough.
