CO2, Temp & RH Monitor (CO2M)

CO2, Temp & RH Monitor (CO2M)

The Flamefast Carbon Dioxide, Temperature and Relative Humidity Monitor provides a bold visual indication of air quality using our signature multicolour 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 visual 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 display colour and relay setpoints.
