CO2 Sensor Application
F2000IAQ-CO2 monitor/controller is used to monitoring and control room CO2 level, as well as room temperature and humidity, provide one or two or three 0~10VDC analog outputs and up to three dry contact outputs . F2000IAQ-CO2 can be as a programmable logical controller to control CO2 level, temperature or humidity, and also as a transmitter DDC/PLC controller or other automation systems. It provides a RS485 communication interface with an independent address to PC or other control systems.
