Aerosense Series CDT-100 Carbon Dioxide Transmitter


Series CDT-100 Carbon Dioxide Transmitter

Series CDT-100, 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 10000 ppm selectable by jumper. It gives analog and RS-485 MODBUS output and supports various functions like recalibration function.
