The Telaire T80415V CO2 Duct Probe Transmitter, 4 in. Probe, 5V Output targets indoor air quality and energy conservation applications. The T8041-5V is easy to install, simple to use, and remains accurate over the expected life of the device using Telaire's patented ABC Logic (Automatic Background Calibration) technology.

The T8041-5V can be used in a broad range of applications including air quality monitoring in buildings. Carbon Dioxide concentration levels in buildings are monitored 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 in the Telaire T8041-5V is based on the absorption of light in a gold-plated reflective light pipe or waveguide diffusion gas chamber. A gas permeable PTFE filter prevents particulate and water contamination of the sensor. Light is absorbed in proportion to the CO2 concentration and the remaining light is measured and converted into an analog signal.
