Aerosense Series CDT-300 Carbon Dioxide Transmitter
Product Applications:
- Demand Control Ventilation in schools, office buildings, hospitals and other indoor environments.
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.
