Extech CO220 Desktop Indoor Air Quality CO2 Monitor

Please Note: That due to the global shortage of CO sensors, we are unable to guarantee a delivery time but pre-orders are being taken to secure stock once supply resumes. We apologise for any inconvenience that this may have caused.

No matter whether you're in an office, a greenhouse or anywhere else, the Extech CO220 allows you to gain a comprehensive view at all times of environmental conditions.

Made for mounting directly on a desk, shelf or similar application, the CO220 constantly monitors carbon dioxide concentration, the level of humidity in the air and provides measurements of air temperature. It also displays the year, month, data and time for quick and easy reference.

Measurements of carbon dioxide levels are displayed as a ppm reading from 0 to 9999ppm and are also signified by Extech's unique facial indication function that shows different levels of CO2 concentration. The following faces are possible:

When CO2 concentration rises or drops below user-settable low/high points the CO220 will emit an audible alarm to instantly alert those around of erratic CO2 conditions.
