Onset’s HOBO MX1102 CO2 logger makes it more convenient than ever to measure and record CO2 in buildings and other non-condensing environments. It measures CO2 from 0–5,000 parts per million (ppm) – and our free HOBOconnect app lets you access data right from your mobile phone, tablet, or Windows computer when within a 100-foot range of the logger.
The MX1102 also features a USB port so it can be used with a computer running HOBOware graphing & analysis software.
Add the MX Gateway for remote access to your data in Onset's cloud-based HOBOlink software.
