CA1510- Controlling the cost of COVID ventilation


CA1510- Controlling the cost of COVID ventilation

Did you know there is a link between the CO2  levels in a room, and the likelihood of COVID-19 being spread amongst the occupants in that room?

Ultimately, if proven, this could lead to a managed way of getting students and staff back into shared spaces with a much-reduced risk of spreading COVID-19 amongst them.

Increased concentrations of  CO2  in an enclosed space indicate insufficient supplies of fresh air due to either inadequate air changes and/or overpopulation of the room.

Numerous scientific studies have proven that aerosols (small droplets) are a major route of transmission of viruses such as COVID-19 and SARS-CoV-2. Active virus particles can float in the air longer and further than originally thought and pose a potential danger.

CO2 is a good indicator of the functionality of the ventilation systems and it had been shown that with a high air exchange, both low CO2 concentrations and low aerosol concentrations can be achieved.

The lower the aerosol concentration, the lower the dose that a person in the room inhales and the lower the risk of infection.

This is particularly applicable in classrooms and lecture halls at universities, colleges and schools, where students and staff sit in relatively close proximity to each other for an extended period, as well as nurseries and day care centres.

The German government is investing €500m in purchasing CO2  monitors and improving ventilation systems in public buildings to help stop the spread of coronavirus. Something we will be suggesting our own government considers.

A BBC news article that highlights the importance the German Government are attaching to air quality, and the role C02 detectors have in achieving that goal, can be found on the link below.


To assist in the fight against COVID-19 Chauvin Arnoux have released the CA1510 portable indoor air quality meter which has proved particularly popular in mainland Europe and is ideal for classrooms/communal areas.

It’s simple to use, measures and records CO2 , relative humidity and temperature, and determines the air quality in rooms on the basis of the CO2 concentration, or on all three measured physical quantities.

Another advantage of the CA1510 is that it monitors and logs all results with a time and date stamp for future reference.

Due to the rise in infection rates of COVID-19, and the part aerosols (small exhaled droplets) play in the transmission of viruses such as COVID-19 and SARS-CoV-2,  air quality, within buildings, is coming under intense scrutiny.


CO2 is an excellent indicator of the efficiency of  ventilation systems, it has been shown that with efficient air exchange both low CO2 and aerosol concentration levels can be achieved, the lower the aerosol concentration the lower dose that the occupants of a room inhale, therefore, the lower the risk of infection.

We are actively promoting the CA1510 to assist in monitoring COlevels, there is a huge market for this product, such as, classrooms /lecture halls, universities, colleges, schools, Government buildings, commercial and retail premises the list and potential is endless.
