OM-NOMAD Data
logger shown larger
than actual size

The NOMAD®Series data loggers
are low-cost easy-to-use portable
dataloggers which can record either
temperature or temperature and
humidity data. Because of its
compact size, it is ideally suited for
applications where space limitations
exist. The NOMAD-T data logger
measures and records temperature
only, using the internal temperature

sensor or the optional remote
sensor. The NOMAD-RH Series
data logger will measure and record
both temperature and relative
humidity simultaneously using the
internal sensors. In addition to the
temperature and humidity, the
NOMAD®data logger will also store
the unit identification number, start
time, sample interval and

E-5

descriptive text relating to the
logging session. The NOMAD
logger also features programmable
alarm limits. If an alarm condition
occurs, an on board LED will light
when the pushbutton is pressed.
Once collected, the data may be
downloaded to a computer through
a standard RS-232 connection
using the Windows software.

Once downloaded to a computer,
the data may then be stored on disk
in a file format which is compatible
with most spread-sheets. The
Windows software also provides
graphic display and print out of the
data. Models are available with
additional memory, to handle longer
logging sessions.
