Test method: Press and hold the lighter switch at the gas inlet of the methane detector and release the air slowly (do not turn on the lighter during emptying). When the concentration reaches the alarm threshold, an alarm is triggered until the volume of the ambient gas falls below the alarm point. Precautions: The warm-up time of the system is about 3 minutes. During this time, the guest test will not work
Protect your families: If a flammable gas leak (kitchen methane / natural gas / camping propane) exceeds the standard, the gas detector emits an 85 dB alarm. It cannot detect carbon monoxide and carbon dioxide. Widely used in restaurants, kitchens, hospitals, hotels, oil factories, garages, gas stations, etc
Note on installation: this gas alarm uses an MCU microprocessor control and an SMT procedure; do not install it in a place with a lot of dust, oil smoke and water vapor, as this can lead to false alarms; choose a suitable place to install the alarm depending on the actual situation
LED digital display and acoustic warning: the gas alarm indicator does not light up normally (in standby mode). When a flammable gas leak is detected, the corresponding number is displayed on the screen. The alarm sounds and flashes red once the concentration is above 5% LEL. The alarm is in different alarm states depending on the concentration of the combustible gas
Durable and energy-saving: plug-in gas detector for home use. Main power supply, which makes installation super easy and convenient. High quality ABS plastic frame, easy to clean. It consumes ≤2 watts of electricity, saves a lot of power
