CO2, Temp & RH Monitor (CO2M) 230V

CO2, Temp & RH Monitor (CO2M) 230V

Complies with REHVA ventilation guidance during COVID-19 pandemic. Click for details

The Flamefast Carbon Dioxide, Temperature and Relative Humidity Monitor provides a bold visual indication of air quality using our signature traffic light backlit display, as well as having a digital readout to display the current levels/concentrations.

CO2 levels are considered a good indication of general air quality, therefore can be used an indicator that any airborne contaminants are being removed.

With a built in mains rated volt free contact, the unit can be easily interfaced with Ventilation and Window Control Systems, as well as Gas Safety Systems. Or it can simply be used as a traffic light indicator to advise further ventilation is required.

The unit offer four pre-set programs, two aimed at ventilation and two aimed at gas safety. These affect the traffic light and relay setpoints.
