Room sensor NLII-iVOC+RH-R is used to monitor air quality inside buildings and power control ventilation (HVAC) systems according to current levels of air pollution. The sensor measures the concentration of gaseous organic substances in the air (VOC) and relative humidity (RH) in air. The sensor can be effectively used in offices, classrooms, restaurants, kitchens, fitness centrums, commercial facilities etc.
The sensor has built-in two separate analog outputs – one for the actual concentration of VOC and the other for the current relative humidity. Sensor also contains one relay. Relay´s response – VOC or RH can be set by shorting jumper. Level of air quality at which the relay switches can be easily adjusted by the rotary switch. Current air quality can be easily checked the by three LED indicators. Eco level means good indoor air quality needed to achieve a sense of well-being together with optimizing energy costs for heating or air conditioning.
