Amphenol Advanced Sensors Ventostat T8031 CO2 Transmitter Sensors

Amphenol Advanced Sensors Telaire® Ventostat® T8031 CO2 Duct-Mount Transmitter Sensors offer accuracy and versatility in a small, easy-to-install form factor. The T8031 series remains accurate for the expected life of the device by using Telaire's ABC Logic™ (Automatic Background Calibration) technology and patented absorption infrared / gas sensing engine. The ABC Logic technology eliminates the need for manual calibration in most applications. Amphenol Telaire Ventostat T8031 CO2 Duct-Mount Transmitter Sensors are ideal for a broad range of applications, including air quality monitoring in buildings to indicate occupancy and provide a ventilation control strategy. This ventilation control facilitates the conservation of energy and indoor air quality maintenance.
