NDIR CO2 Controller for ventilation,greenhouse, grow room


• Features
 Multiple functions and high performance with low prices
 Wall mounting type and duct type selectable
 LCD display detecting both CO2 level and temperature, also relative humidity (optional)
 NDIR infrared CO2 module inside with special ABC Logic Self Calibration System. It makes the CO2 measurement more accurate and more reliable in use.
 15 years lifetime of CO2 sensor
 Microprocessor control, quick response, high precision
 Provide up to three 0~10VDC outputs or relay dry contact outputs, or up to three mix outputs.
 The analog output with two alternatives: linearized over full range output or PID control output
 Different control mode for delays can be selected by user’s application, for example for ventilation or for greenhouse or other applications.
 CO2 range:0~5,000ppm or 0~20,000ppm;
 Modbus RS-485 communication interface optional, 15KV antistatic protection, independent base address setting
 CE-Approval

• 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.
 Hotel, exhibition hall, hospital, shop, restaurant, air port, train station, theater and other public places
 House, villa, office, meeting room, classroom and other places
 Greenhouse, mushroom, grown room and other agricultural applications
 All ventilation systems
