Indoor Air Quality CO2 & Temp Transmitters – Universal Output – LCD Display
- Minimize inventory and save time by combining CO 2 and temperaturemeasurements into one transmitter
- Requires minimal maintenance with Automatic Baseline Correction (ABC) to accountfor sensor drif
- Reduce operation costs using a low energy, reliable, and repeatable CO 2 sensor
- Simplify installation with backplate electrical connection

The Series CDT Carbon Dioxide and Temperature Transmitters accurately monitor the CO2 concentration and temperature in indoor environments to help achieve energy savings. In order to achieve a higher level of accuracy, the Series CDT includes barometric pressure adjustment. The CO2 universal output allows users to select the transmitter output to be 4-20 mA, 0-5 VDC, or 0-10 VDC to work with virtually any building management controller.
For applications that require visual indication, the wall mount configurations of the Series CDT can be ordered with an integral LCD display. To prevent tampering, the action of the buttons can be locked out using an internal dip switch selection. The Series CDT CO2 transmitters are available with a -S option that provides the necessary attributes and parameters to be complaint with DSA requirements for monitoring CO2 levels in schools. There is a front facing LED that illuminates when the CO2 level exceeds 1100 PPM.
For models with resistive thermistors or RTD outputs, please see Resistance vs. Temperature Table.
