NLII-iVOC | Combined sensor VOC/RH Room sensor NLII-iVOC 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) of air. The sensor can be effectively used in offices, classrooms, restaurants, kitchens, fitness centrums, commercial facilities etc. ) measures VOC and RH ) close to the human perception of odors ) compatibility with C02 standard ) 2x analog voltage/current output ) 2x output relay - 2x NO/C ) cascade switching Type of sensor NLII-iVOC NLII-iVOC -R NLII-iVOC +RH NLII-iVOC +RH-R RH output Relay lx switching contact Based on these measurements can be directly controlled ventilation, air conditioning and heat recovery units in an efficient manner.
