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 allows you to access data right from your mobile phone or tablet within a 100-feet range.
The MX1102 also features a USB port so it can be used with a computer running HOBOware graphing and analysis software.
