HOBO®
Dataloggers & Accessories
Onset Computer has two popular dataloggers
models, the HOBO which logs up to 8000 data points
or the Stowaway which logs up to 32,000 data points.
Both have data shuttles to download the dataloggers
and bring data from the field back to your PC in the
office.
HOBO® Event Logger

The reusable HOBO Event records when momentary
contact-closure events happen, storing the time and
date of each event. The HOBO Event datalogger
connects to standard tipping-bucket rain gages to
determine rainfall rates, times and duration. The
HOBO Event eliminates the need to manually read
raingages, saving time and insuring that critical
readings are not missed. Use it to upgrade existing
tipping-bucket systems by replacing counting-type
displays.
