The T6713 Series CO2 sensor combines proven NDIR technology with the small size and low power requirements demanded by today’s OEM manufacturers. It is ideal for applications where CO2 levels need to be measured and controlled for indoor air quality and energy saving applications such as demand control ventilation.

The T6713 is a single wavelength NDIR sensor. It continuously monitors the environment and records the lowest values, then uses automatic background calibration (ABC) logic to offset the sensor’s stored calibration. This means the sensor is best used in applications where the environment periodically drops to ambient (~400ppm) CO2 levels.
