Ultimate Guide to Carbon Dioxide Monitors
Carbon Dioxide monitoring for indoor safety has never been more important, as schools, restaurants and work places are begin re-opening efforts. Over the past 15 months, Forensics Detectors has been dedicated in offering carbon dioxide monitoring products for COVID-19 preparedness planning. These detectors are specifically designed for indoor spaces such as classrooms, gyms and offices. They have adjustable alarm settings to allow users to be compliant with the California Assembly Bill AB 841 CO2 monitoring requirements which mandates CO2 indoor air quality monitoring to reduce COVID-19 transmission and infection risk.
What does a CO2 monitor do?
Carbon Dioxide monitors track the CO2 concentration in a indoor environment. Forensics Detectors has been dedicated in offering carbon dioxide monitoring products for COVID-19 preparedness planning.

Is carbon dioxide linked to COVID transmission?
For many years, carbon dioxide measurements have been used to better understand the airflow and mixing in indoor structures that helps guide the design of cooling, heating, and ventilation systems. High CO2 levels indoors is tied to poor health and lack of fresh air entering an indoor space. Numerous studies have shown links between high CO2 levels and high concentration of airborne bacteria and viruses. Variables such as air exchange rates and exposure times are correlated to and probability of respiratory infections. Hence CO2 monitoring acts as valid proxy. People exhale CO2 when they breathe. The CO2 gas accumulates, especially when an indoor space is not well ventilated, allowing CO2 levels to increase far above the baseline outdoor levels.
What are acceptable CO2 levels?
- Washington State: Requiring CO2 monitoring in restaurants and alarm at 450ppm
- ASHRAE recommends indoor CO2 concentrations be maintained at—or below—1,000 ppm in schools and 800 ppm in offices.
- The Federal Environment Agency of Germany recommends classrooms and offices CO2 concentration should not exceed 1,000 ppm.
- California State: AB841 requiring classrooms to monitor CO2 and alarm at 1100ppm
Of particular interest lately is the California Assembly Bill AB 841 that requires classrooms to monitor CO2 and provide an alert when the carbon dioxide levels in the classroom have surpassed 1100 ppm.
Do you need a carbon dioxide monitor?
If you are concerned about your indoor air quality or have a place of business it would be fitting to have a CO2 monitor to provide assurance to your customers and employees that they are in a safe and healthy environment.
“Carbon Dioxide monitoring means extra safety, something we have taken for granted over the many years, and only now with COVID-19 are we aware of the importance of monitoring CO2 to help prevent airborne pathogen transmission,” Dr. Koz, founder and chief engineer, Forensics Detectors, says. “CO2 is exhaled with aerosols containing pathogens such as SARS-CoV-2 from COVID-19 infected people and can be used as a proxy of virus concentrations in the indoor air as recently discovered by leading researchers.”
How does a carbon dioxide monitor work?
Carbon dioxide monitor works by employing Non Dispersive Infra Red Sensors. Infrared electromagnetic rays interact with CO2 molecules that are absorbed by the CO2 gas molecules at 4.2 micron wavelength. A photodetector then detects the decrease in infrared light received and the output signal is then proportional to the CO2 gas concentration.
