Aerosense Series CDT-300 Carbon Dioxide Transmitter


Series CDT-300 Carbon Dioxide Transmitter

Series CDT-300, Carbon Dioxide Transmitter accurately monitors the CO2 concentration in indoor environments to help achieve energy savings. For increased sensor accuracy, a single beam dual wavelength non-dispersive infrared (NDIR) sensor is used to automatically correct the measurements.

Measurement range upto 70000 ppm selectable by jumper. It gives analog and RS-485 MODBUS output and supports various functions like recalibration function.

Product Applications:

  • Demand Control Ventilation in schools, office buildings, hospitals and other indoor environments.
  • CO2 Sensor: NDIR (Non-Dispersive Infrared) technology
  • Analog Voltage/Current Output: (3-wired) 0/4-20Ma or 0/2-10V- settable by switch
  • Re-Calibration function: 10 minutes’ manual recalibration(MCDL) Or weekly auto-calibration (ACDL) are supported and settable by Switch CO2 ppm measurement range -settable by switch
  • Power: 24VDC, AC
  • Size: 123mmX70mmX43mm
