NDIR Transmitters measure CO2 and temperature.
August 3, 2011 -
Suited for monitoring CO2 concentration and temperature in schools, office buildings, and other indoor environments, Series CDT helps achieve LEED® certification. Transmitters utilize single-beam, dual-wavelength, non-dispersive IR sensor to automatically correct measurement in both occupied and unoccupied buildings against aging effects. Universal outputs allow user to select 4-20 mA, 0-5 Vdc, or 0-10 Vdc to work with virtually any building management controller.

NEW! Series CDT Non-Dispersive Infrared (NDIR) Carbon Dioxide & Temperature Transmitter
Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its NEW SERIES CDT CARBON DIOXIDE AND TEMPERATURE TRANSMITTER.
Series CDT Carbon Dioxide and Temperature Transmitters accurately monitor the CO2 concentration and temperature in schools, office buildings, and other indoor environments to help achieve LEED® certification. For increased sensor life, a single beam dual-wavelength non-dispersive infrared (NDIR) sensor is used to automatically correct the measurement in both occupied and unoccupied buildings against aging effects. The single-beam dual-wavelength sensor technology provides the highest level of accuracy compared to Automatic Baseline Correction methods which can unintentionally shift the calibration based on CO2 levels and barometric pressure conditions. In order to achieve a higher level of accuracy, the Series CDT includes digital barometric pressure adjustment and the ability to field-calibrate the sensor.
Universal outputs allow users to select the transmitter output to be 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC to work with virtually any building management controller. An optional relay with user adjustable set points can be used to control exhaust fans, open actuated windows or dampers, or signal a light or horn.
