ONSET COMPUTER CORPORATION INTRODUCES MAC-COMPATIBLE RAINFALL LOGGING SYSTEM

BOURNE, MA, June 8, 2006 – Onset Computer Corporation, a leading supplier
of battery-powered data loggers for outdoor and underwater monitoring
applications, today introduced the HOBO RG3, a new Mac-compatible rainfall
data logging system that combines a data logging rain gauge with a built-in
data logger.

The new HOBO RG3 system enables agricultural researchers, growers,
stormwater managers and others to record rainfall data right out of the box
without having to purchase and integrate multiple components. It records
data with each tip of the rain gauge bucket – ideal in situations where
peak rainfall rates need to be determined – and an internal temperature
sensor enables the logger to be used in a solar radiation shield to measure
temperature. Other features include:

* Convenient data offload – The HOBO RG3 offloads data to a Mac computer
via a convenient optical interface, which provides high-speed, reliable
data offload in wet environments.~ Its optical design eliminates the need
for failure-prone mechanical connectors found in traditional outdoor data
logging products.

* Large memory – The HOBO RG3’s data logger offers twice the memory of
previous versions, enabling users to record up to 160″ of rainfall data
with a 0.01″ rain gauge. Additionally, because rainfall data is stored as
rain gauge “tips,” memory is not used up during periods of no rain.

* Data shuttle compatible – The RG3 system works with Onset’s new HOBO
Waterproof Shuttle, which allows users to conveniently offload data loggers
in the field and safely transport the data back to a Mac computer for
analysis.

For plotting and analyzing rainfall data, Onset offers HOBOware software, a
highly intuitive graphing and analysis software package for Mac computers.
HOBOware provides a user-friendly graphical user interface and enables
users to quickly and easily view rainfall per hour, day or month, and
export data to spreadsheet programs.

The HOBO RG3 Rainfall Logging system is currently available from Onset and
is priced at $399. The optic-USB base station, HOBO Waterproof Shuttle, and
HOBOware software are all priced separately.
