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 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.
*iOS 8.0–8.3 required; Android app support estimated early Fall 2015.
- Wireless communication via Bluetooth Smart
- Six month battery life at 5-minute CO2 logging rate
- Easy to deploy and offload using free HOBOmobile App
- Visual and audible high & low alarm thresholds
- Self-calibrating CO2 sensor technology ensures optimal accuracy at lower maintenance costs
CO2 monitoring where it counts
Tracking CO2 is a critical aspect of measuring indoor air quality and ensuring a healthy environment. Whether you need to monitor an office space, school, hospital or greenhouse, the HOBO MX1102 makes the process fast, easy and cost-effective.

± 1 minute per month at 25°C (77°F) |
|
Power Source |
4 AA 1.5 Volt batteries (user replaceable) or USB power source (5 V DC, 2 Watts) |
|
Battery Life |
6 months, typical with logging and sampling intervals of 5 minutes or slower; 6 months or less with logging and sampling intervals faster than 5 minutes while logging CO2. Entering burst logging mode will impact battery life. With HOBOmobile use, battery life can be reduced by remaining connected, excessive readouts, checking of Full Status Details, audible alarms, and paging. Visual/audible alarms and other events can have a marginal impact on battery life. |
