ONSET COMPUTER CORPORATION INTRODUCES NEW DATA EXPORT TOOL

BOURNE, MA, April 23, 2008 -- Onset Computer Corporation, the "HOBO" Data
Logger Company, today introduced the Bulk Export Tool, a free plug-in
software utility for the company's Mac-based HOBOware Pro data logger
software package. The Bulk Export Tool saves Mac users time by
automatically converting data log files, which have been collected by
multiple HOBO data logger devices, to text files that can be used by other
data analysis programs. See (http://www.onsetcomp.com/data-logger)

"It's not uncommon for users to have hundreds of HOBO data loggers in the
field, and to want to look at their data in a spreadsheet or with
specialized analysis software," explains Paul Gannett, product marketing
manager for Onset. "Exporting data files one-at-a-time can be very
consuming. With the new Bulk Export Tool, users can now simply click on any
number of data files they wish to convert and the tool will export them all
at once. This is yet another step forward in our continuing series of
time-saving enhancements we're making to HOBOware Pro to make it the
industry's most capable data logger software package."

The Bulk Export Tool is compatible with both Mac and PC versions of
HOBOware Pro software, and is available for free download at
