The Extech CO210 is a desktop indoor air quality monitor and datalogger that measures carbon dioxide (CO2) concentration, air temperature, and relative humidity. It uses a maintenance-free NDIR (non-dispersive infrared) CO2 sensor and presents air quality in parts per million with Good, Normal, and Poor indication, giving a direct readout of ventilation conditions at the bench or desktop.

The CO210 is intended for monitoring air quality in schools, office buildings, greenhouses, factories, hotels, hospitals, and anywhere high levels of carbon dioxide are generated. A typical application is monitoring conference rooms to help ensure proper air ventilation, where rising occupant-driven CO2 levels are an indicator of inadequate fresh-air exchange.

ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois.
