HOBO Bluetooth Low Energy Carbon Dioxide – Temp – RH Data Logger

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 to 5,000 parts per million (ppm) – and our free HOBOmobile app* allows you to access data right from your mobile phone or tablet within a 100-foot range.

The MX1102 also features a USB port so it can be used with a computer running HOBOware graphing and analysis software.
