CO2, Temperature & Relative Humidity Monitor

Product Description
£149.99 inc vat
Maximum quantity available reached.

The Flamefast Carbon Dioxide, Temperature, and Relative Humidity Monitor provides a clear and dynamic indication of air quality through its signature multicolour backlit display and digital readout of current measurements. Designed for functionality and ease of integration, the monitor measures CO₂ levels, temperature, and relative humidity, offering actionable insights for maintaining optimal indoor air quality.

CO₂ levels serve as a reliable proxy for overall air quality, helping identify when additional ventilation may be required to remove airborne contaminants. The unit includes a mains-rated volt-free contact, making it compatible with ventilation systems, window controls, and gas safety systems. Alternatively, it can function as a standalone visual indicator to prompt further ventilation.

Four pre-set programs are available, tailored for ventilation or gas safety applications, which adjust display colours and relay setpoints for different environments.
