This wall-mounted natural gas detector is designed to monitor methane (CH4) concentrations and provide an early warning in case of dangerous gas levels. With an operational voltage of AC220V and a power consumption of ≤2W, this detector is suitable for residential and commercial settings. It features a sensor with a 10-year lifespan and a product life expectancy of over 3 years, ensuring long-term reliability. The device triggers an alarm at 9% LEL (Lower Explosive Limit), equivalent to 3500ppm, within a rapid response time of 30 seconds. The alarm system includes sound and visual alerts, with a buzzer sound level exceeding 70dB and LED indicators that display red, green, and yellow lights for operational status. It is designed to operate in various environmental conditions, with a temperature range of -10°C to 55°C and humidity tolerance up to 95% RH without condensation. Installation is simple, with the unit being wall-mounted within 1.5 meters of the gas source. The product complies with the GB 15322.2-2019 standard.
