Wall Mount CO2 Humidity Temperature Transmitters Amphenol T8100 E HD for Commercial HVAC Ventilation
Product Overview
The Telaire 8000 Ventostat series offers wall-mount CO2, humidity, and temperature transmitters designed for controlled ventilation in commercial HVAC applications. These transmitters help maintain indoor air quality, prevent energy waste from over-ventilation, and ensure a healthy, productive environment. Featuring patented sensing technologies like Absorption Infrared Gas sensing and ABC Logic self-calibration, they provide high accuracy and minimize maintenance needs. The two-piece design facilitates easy installation and replacement without rewiring. Available in various configurations, including models with displays and BACnet output, they are ideal for controlling specific areas such as conference rooms, classrooms, and meeting halls.
