OM-DVTH shown larger
than actual size.
The OM-DVTH temperature/relative
humidity data logger with display
is an easy-to-use, versatile device
which can be used for a wide
range of logging applications.
The OM-DVTH records and instantly
displays trends for temperature,
humidity and dew point. With the
OM-DVTH you can monitor real
time measurements for instant
environmental conditions. When
you’re ready, download over
40,000 data points to your PC for
further analysis. Data logging has
never been this visual.
The OM-DVTH is capable of
sampling as fast as once per
second or as slow as every 18
hours.
A total of 43,344 temperature
measurements can be stored in
the data logger memory if only
temperature is measured, or 21,672
measurements for temperature,
humidity and dew point if all three
parameters are measured.
Easy-to-use Windows software is
included with the OM-DVTH. The
software is a full-featured program
that allows you to set up all data
logger functions including sampling
rate, logging duration, start mode,
logging mode, and high and low
temperature and relative humidity
alarm values. Once data has been
logged, the program then allows you
to download data from the logger,
plot the data and export the data to
an ASCII text or Excel file format for
further analysis.
