CO2 is exhaled with aerosols containing pathogens such as SARS-CoV-2 from COVID-19 infected people. Therefore, CO2 measurements can be used as a proxy for indoor virus concentrations - as shown by research from the University of Colorado & Harvard School of Public Health. Various government legislatures and professional organizations such as ASHRAE recommend indoor air quality monitoring to reduce the risk of COVID-19 infection. The Technical University of Berlin shows that increasing uncontaminated air reduces indoor concentrations of CO2 and other aerosols. In turn, this strategy of fresh air ventilation lowers one's infection risk. Description: The FORENSICS DETECTORS CO2 monitor is an easy-to-use and accurate device. This detector continuously monitors indoor CO2 levels - perfect for your classroom, business, gym, or office to minimize the risk of pathogen distribution. Complies with the AB841 1100 ppm alarm level and max feature requirement. The wall plug-in model uses direct power from a wall outlet. The monitor also detects humidity, temperature, and time. Your CO2 monitor is already calibrated so just turn it ON and GO! The monitor incorporates a high-quality advanced NDIR sensor that detects CO2 with a 1 ppm resolution.
