AIRSENS CO2: room measurement probe

Description:
  • Non-dispersive infrared (NDIR) measurement.
  • 2 possible modes of use, selection by switches:
    • Control mode: using the 0-10V output of the probe, the ventilation flow rate is proportional to the CO2 rate.
    • All or little mode: using the relay output, the ventilation flow rate is minimum below the CO2 threshold adjustable by potentiometer (factory value 1200 ppm) and maximum above this threshold.
  • Visualization of the CO2 concentration by LED:
Slave mode All or little mode
Green Value ≤ 800 ppm Value < Setpoint set
Orange Value between 800 and 1200 ppm Not used
Red Value> 1200 ppm Value > Setpoint set
  • Automatic calibration.
  • Communicating Modbus RTU RS485.
