Monitor rooms or zones for air quality with a HOBO CO2 data logger

Onset's award-winning MX1102 logger makes it more convenient than ever to measure and record CO2 levels in buildings and other non-condensing environments.

Equipped with a self-calibrating sensor, it measures 0-5000 ppm, and you can access the data right from your phone, tablet or laptop using our HOBOconnect mobile app. A USB port lets you directly connect a computer with our HOBOware graphing and analysis software for more robust modeling and analysis of your data.
