The OMEGA®RD8900 Series
paperless recorder offers real time
display of data in a variety of
formats on a high resolution (VGA)
color TFT display. The user friendly
unit with plug & play cards can
easily be set to monitor, record, and
evaluate any application. The user
can access data on the screen, as
well as from a remote site via the
standard ethernet or optional
RS232/422/485 serial interface.
The historical data may be stored in
a flash ROM, compact flash card, or
collected in a remote host PC for
evaluation and print out. The unit's
compact size saves space and
requires less than 7" behind a panel.
