Monitor air quality

Web-IO CO2 is a network-capable measuring instrument for detecting carbon dioxide concentration in the ambient air.

For long-term, continuous detection of the CO2 concentrations it is equipped with an internal data logger, and the measuring data can be sent to the W&T cloud as well. The alarm function sends messages when configurable limits are exceeded.

The measuring range of 0-5,000 ppm is suitable for monitoring the indoor air in schools, daycare centers, retirement homes and office buildings. Applications from agriculture and horticulture include stall climate detection and greenhouse monitoring.
