HOBO MX1102A Bluetooth Low Energy Carbon Dioxide/Temperature/Relative Humidity Data Logger
Overview:
Onset’s HOBO MX1102A 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 MX1102A also features a USB port so it can be used with a computer running HOBOware graphing and analysis software.
Highlight:
- Wireless communication via Bluetooth Low Energy (BLE) Technology
- 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 NDIR CO2 sensor technology ensures optimal accuracy and lower maintenance costs
- Memory up to 84,650 measurements
- Patented connectivity technology
