ONSET COMPUTER CORPORATION ANNOUNCES NEW MAC-COMPATIBLE DATA LOGGERS FOR
OUTDOOR MONITORING

BOURNE, MA, October 10, 2006 – Onset Computer Corporation, a leading
supplier of battery-powered data loggers, today announced the HOBO Pro v2
Series, a family of four Mac-compatible, weatherproof data loggers designed
for use in a broad range of outdoor temperature and humidity monitoring
applications.

Slightly larger than a pocket-sized flashlight, the new HOBO Pro v2 loggers
address the need among professional researchers for a portable data logger
that can withstand harsh outdoor and condensing environments. Example
applications include field site evaluations, ecology studies, and
microclimate monitoring.

Key features include:

– Robust and replaceable RH sensor, which provides superior recovery from
condensing conditions.

– Fast, reliable data offload via a high-speed optic-USB interface.

– Compatibility with Onset’s HOBO Waterproof Shuttle for fast, safe data
transport in the field.

A choice of four loggers is offered, including a temperature/RH internal
sensor model, a temperature/RH external sensor model, a dual external
temperature sensor model, and a one-internal/one-external temperature
sensor model. Each HOBO Pro v2 logger can store 42,000 measurements and
runs for up to three years on a single, user-replaceable battery.

For plotting and analyzing 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 plot, analyze and print data files, as well as
export data to spreadsheet programs.

HOBO Pro v2 Series loggers are currently available from Onset and priced
from $129. The optic-USB base station, HOBO Waterproof Shuttle, protective
boots, and HOBOware software are priced separately. Please visit
