PRINCIPLES The CL11 data logger evaluates air quality with the combined measurements of CO2, humidity, and temperature. These measurements are important to understand Indoor Air Quality (IAQ) in classrooms, conference and waiting rooms, as well as any indoor areas where people gather. A high concentration of carbon dioxide can develop quickly when closed rooms with insufcient ventilation are lled with people. Carbon dioxide (CO2) is a colorless and odorless gas that exists in the earth’s atmosphere and which is dangerous in high concentrations. The proportion of CO2 in natural ambient air...
