Product Overview
CDT-2D40 is a series CDT carbon dioxide and temperature transmitter 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. Typical applications include demand control ventilation in schools, office buildings, hospitals, and other indoor environments, LEED® certification.
- Minimize inventory and save time by combining CO2 and temperature measurements into one transmitter
- Reduces the number of devices mounted in the space with integral humidity and temperature sensors
- Requires minimal maintenance with Automatic Baseline Correction (ABC) to account for sensor drift
- Reduce operation costs using a low energy, reliable, and repeatable CO2 sensor
- Simplify installation with backplate electrical connection
- NDIR, 15 year life expectancy
- 0 to 2000PPM CO2 range
- Duct mount configuration
- 4-20mA / 0 to (5 or 10)VDC CO2
