The OM-EL-USB-2-LCD is a standalone data logger
that measures and stores up to 16,379 relative humidity
and 16,379 temperature readings over 0 to 100% RH
and -35 to 80°C (-31 to 176°F) measurement ranges.
The high contrast LCD can show a variety of temperature
and humidity information.
At the touch of a button, the user can cycle between
the current temperature and humidity, along with the
maximum and minimum stored values for temperature
and humidity. In addition, logging and alarm status is
shown using two high intensity LEDs. The data logger
is supplied with a long-life lithium battery, which can
typically allow logging for up to 1 year.
The user can easily set up the data logger and download
logged data by plugging the unit into a PCs USB
port and using the supplied Windows software. Data
logger parameters that can be set up include data
logger name, °C or °F temperature units, logging rate
(10 sec, 1 min, 5 min, 30 min, 1 hr, 6 hrs, 12 hrs), high
and low alarms, immediate, delayed or push-to-start
logging, display off, on for 30 seconds after button
press, or permanently on, and data rollover (allows
unlimited logging periods by overwriting the oldest
data when the memory is full). Downloaded relative
humidity, temperature and dew point data saved in
text format can be graphed, printed and exported
to other applications for further analysis.
