The Ventostat® T8031/T8041 duct-mount and Airestat® T5000 Series wall-mount carbon dioxide (CO2) transmitters are easy to install and simple to use. They remain accurate over the expected life of the device utilizing the Automated Background Calibration (ABC) Logic® technology, said the company. The T8031 fits into 6-inch return air ductwork. For larger ducts, the T8041 duct-mount probe can be used to measure CO2 concentrations. The Airestat 5000 Series offers user-definable thresholds and a visual limit LED indicator (green, yellow, and red) for measured CO2 concentrations. The T8031, T8041, and T5000 Series offer a standard analog 0- to 10-V output.
