CO2, Temp & RH Monitor (CO2M) 230V

CO2, Temp & RH Monitor (CO2M) 230V

The Flamefast Carbon Dioxide,Temperature and Relative Humidity Monitor provides a bold visual indication using a traffic light backlit LCD, as well as having a digital readout to displays the levels/concentrations.

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

The unit offers four user selectable programmes for different applications; two aimed at Ventilation and a further two aimed at Gas Safety. Custom software profiles are also available to control the audible alarm, the relay set point and the traffic light changeover levels, based on any combination of CO2, Temp & RH (CO2 default).
