The Telaire Ventostat 8000 series wall-mount transmitters offer simultaneous measurement of CO2, humidity, and temperature, designed for controlled ventilation in commercial HVAC applications. These devices are crucial for maintaining indoor air quality, occupant health, and energy efficiency by preventing over-ventilation. Featuring a patented Absorption Infrared Gas sensing engine and ABC Logic self-calibration system, they provide high accuracy with minimal maintenance, including a lifetime CO2 calibration guarantee for T8100 and T8300 models. Their two-piece design allows for easy installation and replacement without rewiring. Available in various configurations including models with displays and BACnet output, they are ideal for controlling specific areas like conference rooms, classrooms, and meeting halls.
