5000 CO2 Monitors to Glasgow Schools

CO2 for Schools

by | Sep 27, 2022

Duomo Awarded Prestigious Contract To Provide 5000 CO2 Monitors to Glasgow Schools.

In 2021, in the midst of the COVID19 pandemic, several trials were conducted to better understand the effect of air quality (ventilation) on pathogen transmission. This research concluded that maintaining good air quality was a key tool in the fight to reduce transmission.

These trials were based on a variety of technologies, but with primary focus given to non-dispersive infrared (NDIR) based CO2 sensors.

Led by the Department for Education (DfE), the research resulted in a CO2 monitor provision requirement for all schools. Empowering schools to balance air quality with classroom temperatures which can be a problem during colder months.

The study also found that, while other ventilation strategies (e.g. opening windows) can be helpful, they are not as effective as using an NDIR sensor to monitor and control air quality.

The product specification that was developed, was based around the units used for the research and issued. However, it was apparent from the early stages that the funding required to supply schools with these sensors wouldn’t be available. The specification, therefore, was revised to allow for lower-cost solutions to be sourced and provided.

The feedback from school teachers on these low-cost USB and mains operated units was varied. With reports of quality problems, frozen monitors, reliability issues and units falling out of calibration which resulted in many being disconnected.

Balanced Glasgow City Council approach selecting CO2 for Schools

The process for selecting practical product requirements, carried out by Glasgow City Council. This was more balanced and analytical with a high level of support provided by both Duomo and SAF Tehnika.

The Scottish Government’s careful and unbiased approach to choosing a solution was an excellent decision. They carefully considered all options regardless of cost which led them choosing one particular stand-out product; The Aranet4 Home, considered one of the best CO2 Monitor solutions available.

As a result of this research and support, Duomo are delighted to have received an order from Glasgow City Council to supply 5000 CO2 Monitors to Glasgow Schools. The Aranet4 Home units replace some of the unreliable USB monitors that were previously used by the Council.

Duomo also went above and beyond by offering custom CO2 thresholds and short lead-times demonstrating their commitment to providing quality products that meet customer needs in a timely manner.

Duomo Sales Director Jonathan Farmer commented:

“The order is a direct reflection of the support we have and continue to provide to both Government and private entities. The order for Glasgow City Council has only been made possible due to the high level of support offered directly by SAF Tehnika of Latvia for whom we represent.”

Benefits of the Aranet4:

  • Battery powered, with battery life approaching 5 years (at 10min samples)
  • Senseair Sunrise NDIR Sensor (low power, high accuracy)
  • Paper display with traffic light display showing CO2, Temp and RH
  • ABC Calibration
  • Bluetooth connectivity for data extraction
