The NLII-TVOC-R Room Sensor is designed 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 measures the concentration of total volatile organic compounds (TVOC = Total VOC) in the air and the relative humidity (RH) of the air. It is suitable for offices, classrooms, restaurants, kitchens, fitness centers, commercial properties, households, restrooms, changing rooms, etc. This is an extension of the basic product NLII-TVOC with a relay output.
