HOBO data loggers requires HOBOware software (USB interface cable included w/CD purchase) and a communications device. See compatible items below.
The HOBO UX100-023 External Temperature/Relative Humidity data logger records temperature and relative humidity in an indoor environment with its external sensor. Ideal for monitoring occupant comfort in office buildings, tracking food storage conditions in warehouses, logging temperature trends in server rooms, and measuring humidity levels in museums.

Highlighted Features

• Easy-to view LCD display
• Large memory capacity
• Visual high & low alarm thresholds
• New Burst and Statistics logging modes
• User-replaceable Relative Humidity sensor
• Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis
