CO2 & Temp Monitor (CO2M)

CO2 & Temp Monitor (CO2M)

The Flamefast Carbon Dioxide, Temperature & Relative Humidity Monitor provides a bold visual indication using a traffic light LCD, as well as having a digital readout for all three signals.

Using the built in Volt Free Contact, the unit can be easily interfaced with Ventilation and Window Control Systems, as well as Gas Safety Systems. The unit can also simply be used as a traffic light indication to raise awareness of high CO2, Temp or RH levels.

The CO2M offers four user selectable programs for different applications; two aimed at Ventilation and two aimed at Gas Safety. Custom software profiles can also be provided to adjust the alarm and traffic light set-points as well as the relay configuration. The relay and traffic light can be configured to activate based on any combination of CO2, Temp & RH (CO2 only as default).
