Monitoring CO2, temperature, relative humidity and atmospheric pressure : Aranet4 Pro
Aranet4 is an easy to use CO² monitoring device that lets you know right away if the ventilation is sufficient and whether you are at an elevated risk of SARS-CoV-2 infection via aerosols. Visual color indicators, as well as a sound alarm, will notify you when action (opening windows, turning up the ventilation or leaving the room all together) must be taken.
Schools and universities often are hotbeds for COVID-19 spread. This is no surprise since there are many people in closed environments like classrooms, so it can be a nightmare to ensure all safety precautions are met.
