The OM-EL-GFX Series portable temperature/
humidity data loggers measure and store up to
252,928 readings. Using the included Windows®
control software users can quickly set up the data
logger and view downloaded data by connecting
the device to the computer’s USB port.
OM-EL-GFX-DTP,
dual channel
thermistor data
logger with
graphic display.
The data logger features a high contrast graphic LCD
display and three input buttons. This allows users to
start, stop and restart the data logger using on-screen
menus. The menu also provides real-time analysis of
data either as a data summary (showing highest and
lowest readings and alarm conditions) or as a graph
that updates as new data is added. The maximum and
minimum readings and also the time and date these
are valid from can be displayed on the LCD display
by using the info button. If desired, the user can then
reset the maximum/minimum readings shown. Each
time the maximum/minimum readings are reset while
logging, an “event marker” is created in the data. When
the data has been downloaded to the computer these
events can be viewed on the graph (event markers),
and they also appear in the data file associated with
the corresponding log when the reset took place. This
can be useful as an audit/validation tool for certain
applications where procedures mandate that a regular
physical check of the logger/statistics have taken
place. Multiple data logging sessions can be stored on
the device ready for upload to the computer at a
later time.
The data logger’s robust design provides IP67
waterproof protection (OM-EL-GFX-1,
OM-EL-GFX-2 and OM-EL-GFX-2-PLUS only).

CONTROL SOFTWARE
The Easylog USB control software is easy to install and
use, and runs under Windows XP, Vista, 7 and 8. The
software is used to set-up the data logger as well as
download, graph and export data to Excel. Each stored
logging session is saved as a separate file.
The software allows the following parameters to be
configured:
• Logger name
• Measurement parameter (ºC or ºF)
• Logging Rate (user-selectable between 10 seconds and 1 hour for OM-EL-GFX-1, OM-EL-GFX-2 and
OM-EL-GFX-2-PLUS and between 2 seconds and
1 hour for OM-EL-GFX-DTC, OM-EL-GFX-TC and
OM-EL-GFX-DTP)
• High and low temperature alarms
• Immediate, delayed, push-button or temperature triggered start mode
• Disable or enable LEDs and audible alarm with
delayed activation
• Display and backlight behavior after button press
These data loggers do not lose stored readings when
the batteries are discharged or when the batteries are
replaced; however, the data logging process will be
stopped. If the batteries are changed within a 2 minute
window the data loggers will retain its settings (internal
clock and logging mode). This will allow logging to be
restarted without additional connection to a PC via USB.
Windows software shows data in graphical format.
