CO2MC – Carbon Dioxide, Temp & RH Monitor & Controller

Carbon Dioxide Wall Mounted Sensor Range

Available Sizes/Options

  • 24V
  • 230V

The Duomo CO2MC has been developed to monitor levels of Carbon Dioxide in offices, schools or kitchens. The Monitor can be set to change the backlit display from Green to yellow to Red progressively as levels of Carbon Dioxide increase. The location of the monitor, for example in classrooms or food technology rooms, dictates different thresholds for each colour change threshold. Not all classrooms or offices have an automatic ventilation system based on air quality and CO2 levels. The CO2MC allows occupants to determine when additional ventilation is required; putting control back into the hands of the teachers.
