CO2 Humidity Temperature Sensor Amphenol T8100-E-D-GN-R Wall Mount for Demand Controlled Ventilation
Product Overview
Telaire Ventostat 8000 series wall mount transmitters are designed for monitoring CO2, humidity, and temperature in occupied building HVAC applications. These devices are crucial for demand-controlled ventilation, preventing energy waste from over-ventilation while maintaining indoor air quality. They are ideal for controlling specific areas like conference rooms, classrooms, and meeting halls. The series features a patented Absorption Infrared Gas sensing engine for high accuracy and a patented ABC Logic self-calibration system that eliminates the need for manual calibration in most applications, offering a lifetime CO2 calibration guarantee for T8100 and T8300 models. The two-piece design allows for easy unit replacement without rewiring, and a modern enclosure with optional customized branding is available.
