(GST 18% Exclusive)
Dwyer CDT-2D40 Duct Mount Carbon Dioxide Transmitter accurately monitors the CO2 concentration in indoor environments to help achieve energy savings. For increasing sensor accuracy, a single-beam dual-wavelength nondispersive infrared (NDIR) sensor is used to automatically correct the measurement in both occupied and unoccupied buildings against light source aging effects.
Application: Demand control ventilation in schools, office buildings, hospitals, and other indoor environments

Ace Duct Mount Temperature Humidity Sensor
Dwyer CDT-2D40 Duct Mount Carbon Dioxide Transmitter is Single-beam dual-wavelength sensor technology provides the user the highest level of accuracy when compared to Automatic Baseline Correction methods which can unintentionally shift the calibration based on CO2 levels and barometric pressure condition. In order to achieve a higher level of accuracy, the CDT includes digital barometric pressure adjustment and the ability to field-calibrate the sensor. The Push buttons are standard on all configurations of the transmitters.
Features of Dwyer CDT-2D40 Duct Mount Carbon Dioxide Transmitter :
- Single beam dual-wavelength NDIR sensor eliminates draft due to light source aging
- Integral passive temperature outputs reduce the number of devices mounted in the space
- Service display tool available for models without an integral LED
- Optional integral display and relay output
