Extech CO210 Desktop IAQ CO2 Datalogger

The Extech CO210 Desktop IAQ Datalogger measures and stores carbon dioxide (CO2), air temperature, and relative humidity readings. Up to 5333 data points of each of the three parameters can be stored, for a total of 159999 data points stored overall. The maintenance-free CO2 sensor and small size (4 inches in diameter) of the CO210 Datalogger allows users to set it and forget it. In addition to an Indoor Air Quality status display of Good, Normal, or Poor, the unit also displays the current year, month, date, and time. Automatic baseline calibration and manual calibration in fresh air ensure that readings from the CO210 are as accurate as possible. The CO210 IAQ Datalogger is well-suited for obtaining measurements in schools, offices, homes, greenhouses, or anywhere elevated levels of CO2 might be common.
