HOBO Carbon Dioxide/Temp/RH Data Logger
Overview
Measures and records CO2 in buildings and other non-condensing environments. Works with our free HOBOconnect app for data access right from your mobile phone, tablet, or Windows computer when within 100 feet of the logger.
This logger also features a USB port so it can be used with a computer running HOBOware graphing & analysis software.
Purchase an MX Data Plan to get more out of your data and access it from anywhere using the LI-COR Cloud software platform (formerly HOBOlink)! You can also purchase the MX Gateway station, which automatically sends your logger’s data to LI-COR Cloud.

Logger Operating Range
0° to 50°C ; 0 to 95% RH (non-condensing)
32° to 122°F ; 0 to 95% RH (non-condensing)
Logging Rate
1 second to 18 hours
Logging Modes
Fixed interval (normal, statistics) or burst
Memory Modes
Wrap when full or stop when full
Start Modes
Immediate, push button, date & time, or next interval
Stop Modes
When memory full, push button, date & time, or after a set logging period
Time Accuracy
±1 minute per month at 25°C
±1 minute per month at 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 app use, battery life can be reduced by remaining connected, excessive readouts, audible alarms, and paging. Visual/audible alarms and other events can have a marginal impact on battery life.
