The combined room sensor NLII-CO2+TVOC-R is used for continuous monitoring of indoor air quality in buildings and for subsequent control of the performance of ventilation (HVAC) systems according to the current level of air pollution. The sensor monitors the concentration of Carbon Dioxide (CO₂) and the concentration of total Volatile Organic Compounds (VOCs) in the air (known as TVOC = Total VOC). The measurement of TVOC is in accordance with EPA and UBA standards. The TVOC output can be configured as a combined CO₂/TVOC output.
