Featuring a loud 85dB alarm and a clear LED display that shows real-time gas concentration levels, it ensures immediate awareness of hazardous leaks. Designed with energy-saving semiconductor sensors and housed in fireproof ABS plastic, it offers reliable, low-power operation suitable for kitchens, garages, hotels, and more. Easy to install with a standard British 3-pin plug, this detector is a must-have for proactive safety in any professional or home environment. ## Description Yes. After receiving the alarm, please request a copy of the certificate from us. Our alarms have a 180-second warm-up period. Do not operate the device during this period, as it will not respond. For your safety, we don't recommend using the above test method. Besides, the alarm won't sound unless reaching the threshold. ## 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 ## Technical Specifications | Specification | Value | |---------------|-------| | Alarm | Visual | | Asin | B07R7H6QTZ | | Best Sellers Rank | 12,659 in DIY & Tools (See Top 100 in DIY & Tools) 4 in Gas Detectors | | Brand | D MODUN | | Colour | White | | Country Of Origin | China | | Customer Reviews | 4.4 4.4 out of 5 stars (460) 4.4 out of 5 stars | | Item Dimensions D X W X H | 5.9D x 6.9W x 12.1H centimetres | | Item Weight | 150 Grams | | Manufacturer | MODUN | | Material | ABS | | Model Number | BRJ-502 | | Number Of Items | 1 | | Operating Humidity | 97 percent | | Part Number | BRJ-502 | | Power Source | AC | | Product Style | Compact | | Sensor Type | Gas Sensitive Semi Conductor | | Unit Count | 1.0 count | | Upper Temperature Rating | 50 Degrees Celsius | ## Product Details - **Alarm:** Visual - **Brand:** D MODUN - **Colour:** White - **Item weight:** 150 Grams - **Operating humidity:** 97 percent - **Power source:** AC - **Product dimensions:** 5.9D x 6.9W x 12.1H centimetres - **Sensor type:** Gas Sensitive Semi Conductor - **Style:** Compact - **Upper temperature rating:** 50 Degrees Celsius ## Images ![D MODUN Gas Detector, Natural Gas/LPG/City Coal Gas Leak Detector, 3-Pin Plug-in Gas Monitor with Sound Alarm and LED Display, Methane Propane Butane Combustible Gas Alarm for Kitchen RV Garage Hotel - Image 1](https://m.media-amazon.com/images/I/51LiQL8wmkL.jpg) ## Available Options This product comes in different **Colour Name** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Saved our lives *by on Reviewed in the United Kingdom 11 July 2026* 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! ### ⭐⭐⭐⭐⭐ Life Saver *by on Reviewed in the United Kingdom 17 January 2024* I purchased this alarm for my 81 year old mum who has lost her sense of smell and has a tendency to knock the gas knobs on her cooker. I was a little dubious about this alarm working from having read the reviews, however, I decided to purchase it anyway as previously, by sheer luck, a family member went to visit mum who had gone to sleep not realising she had knocked the gas knob to ‘on’! So far it has worked brilliantly, whether it takes a little while to detect the gas or not. Being elderly, mum does fall asleep but the alarm has woken her when it’s detected gas. I can truly say it’s saved her life as going by last time, the gas had been on for 4hrs and the fire service had to go in with gas masks to open all the windows and doors with mum having to sit outside for 2hrs before they let her go back in. The most important thing is this device works and if it’s a choice between not having one and having one, I’d certainly opt for the latter. ### ⭐⭐⭐⭐⭐ A nice simple safety device *by on Reviewed in the United Kingdom 29 March 2022* 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. ## Frequently Bought Together - Gas Detector, LPG | Natural Gas | Coal Gas Leak Detector, 3-Pin Plug-in Sensor Gas Monitor with Sound Alarm and LED Display, Methane Propane Butane Combustible Gas Alarm for Kitchen Hospital Garage - Kidde 5CO Carbon Monoxide Alarm and Detector with AA Batteries - 10 Year Sensor Life CO Alarm for Home - Gas Detector Alarm, LPG | Natural Gas | Coal Gas Leak Detector, Plug-in Sensor Gas Monitor with Sound Alarm and LED Display, Methane Propane Butane Combustible Gas Alarm for Kitchen Garage --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/139713472-d-modun-gas-detector-natural-gas-lpg-city-coal-gas](https://www.desertcart.sn/products/139713472-d-modun-gas-detector-natural-gas-lpg-city-coal-gas) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-17*
