◦ combined sensor of CO2+RH
◦ measuring range of CO2 to 5 000 ppm
◦ power supply 24 V AC/DC
◦ 2x analog output, 1x relay
Combined sensor NLII-CO2+RH-R is used to monitor air quality inside buildings and power control ventilation (HVAC) systems according to current levels of air internal air quality. The sensor measures concentration of carbon dioxide (CO2) and relative humidity (RH) in air. It can be effectively used in offices, classrooms, shopping centers, homes, restaurants, fitness centers, commercial buildings, etc.
Sensor provides two analog outputs, first one for RH and second for CO2 level indication. It can measure to 5 000 ppm. It is possible to select the response of the relay to either CO2 or RH by jumper. Relay trigger level can be set by rotary switch. Based on these measurements, it is possible to directly control the ventilation, air conditioning and heat recovery units.
Three LED indicators indicate in easy way actual internal air quality level. The level of eco indicates a good level of air quality necessary to achieve a sense of well-being together with optimized power consumption required for heating or air conditioning the interior.
