The OM-EL-USB-RT is a real time
temperature and humidity monitor
that displays real time temperature
and humidity data on your computer
via the Windows®control software
(it is not a data logger and does
not have any internal memory).
The software displays the
temperature, relative humidity
and dew point in real-time and
saves it to a file which can store
up to 7 day’s worth of data. This
data file is overwritten at the
beginning of each new logging
session. The software provides the
option for the user to save the data
permanently to the computer’s hard
drive. Temperature, relative
humidity and dew point data can be
graphed, printed and exported to
other applications such as Excel.
The OM-EL-USB-RT Windows
control software provides an
environment whereby the user can
view the current temperature and
relative humidity and graph either
the current data file or previously
saved files. Users can set up high
and low alarms for temperature and
humidity within the software which
can send emails, text alerts or
audile alarms via the PC’s internal
speaker. The software can also
show the current temperature and
humidity in the notification area
within the Window’s tool-bar. Right
clicking on the OM-EL-USB-RT icon
in the notification area enables the
user to access the full functionality
of the software.
