The STRAJ S51A2L is a stationary gas detector designed to monitor environments for methane and carbon monoxide. Operating on a voltage of 12-24V, this device provides essential safety in households, communal areas, industrial spaces, and boiler rooms, provided they are non-explosive zones. It triggers an alarm when methane reaches 0.5% (10% LEL) or when carbon monoxide levels hit 0.01% (100 ppm), and it also responds to temperatures reaching +55°C. To ensure reliable detection, the unit requires a warm-up period of up to 30 minutes, during which the methane response time is a maximum of 300 seconds. Once fully operational, it reacts quickly to hazards, with an alarm response time of 30 seconds for methane and 60 seconds for carbon monoxide. The shock-resistant plastic housing protects the internal components, while built-in light and sound indicators alert you to danger with a siren that reaches at least 85 dB at a distance of 1 meter. This model is built in compliance with the DSTU EN 50194 standard, offering a dependable way to monitor air quality and gas leaks in your utility spaces.
