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 and 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.
