Gas Detector, Plug-in Sensor Gas Monitor with Audible Alarm and LED Display

Multi-Gas Detector-- The gas detector is primarily used to detect natural gas (main components: methane), LPG (main components: propane, butane), and town coal gas (alkanes, olefins, arenes). When the combustible gas leak exceeds the standard, the gas detector will emit a continuous, accelerating audible alarm at 85 dB. It cannot detect toxic gases such as carbon monoxide. Digital LED Display and Audible Warning-- Gas detectors do not display values ​​under normal conditions. If a flammable gas leak is detected, the numbers 400 to 9999 and HHHH may be displayed on the screen. The alarm will sound and flash red once the concentration exceeds 7% of the LEL (Lower Explosive Limit). The alarm will be in different alarm states depending on the concentration of flammable gas. Durable and Energy-Saving-- Plug-in gas alarm designed for home use. Mains powered, making it super easy and convenient to install. This detector is mold-resistant, pest-resistant, and corrosion-resistant. ABS plastic frame, easy to clean. Uses less than 3 watts of electricity, a considerable energy saving. Widely used in restaurants, kitchens, hospitals, hotels, oil plants, garages, gas stations, and so on. Test Method-- Press and hold the ignition switch located at the gas inlet of the methane detector, then slowly deflate the device (do not turn it on during deflation). When the concentration reaches the standard value, the alarm will sound until the volume of gas in the environment falls below the alarm point. Precautions: The system requires approximately 2-3 minutes to warm up. The gas test will not function during this time.
