The new generation of duct mount Telaire Ventostat T8041 CO2 transmitters is targeted to indoor air quality and energy conservation applications. The Telaire Ventostat T8041 CO2 transmitter offers accuracy and versatility at an affordable price. This exceptionally sleek, low-profile transmitter is easy to install, simple to use, and remains accurate over the expected life of the device utilizing Telaire's patented ABC Logic™ (Automatic Background Calibration) technology.

The duct mount Telaire Ventostat T8041 CO2 transmitter can be utilized in a broad range of applications, especially air quality monitoring in commercial buildings. Carbon dioxide concentration levels in buildings can be monitored with the T8041 to provide an indication of occupancy and to drive a ventilation control strategy. An effective DCV (Demand Controlled Ventilation) strategy will conserve energy and maintain indoor air quality.

The technology behind the Telaire Ventostat T8041 CO2 transmitter is based on the absorption of light in a gold-plated reflective light pipe or waveguide diffusion gas chamber. A gas permeable Teflon filter prevents particulate and water contamination of the sensor. Light is absorbed in proportion to the carbon dioxide concentration, and the remaining light is measured and converted into a 0-10V analog signal.

Duct mount Telaire Ventostat T8041 CO2 transmitters are designed to be installed in HVAC return air ducts. It offers simplicity in design and installation, with all mounting hardware and installation instructions included with each unit.
