The OM-EL-USB Series of data
loggers includes models for
temperature, temperature/relative
humidity, voltage, and current
measurement. The user can easily
set up the data logger and download
the stored data by plugging the
module into a PC’s USB port and
running the easy-to-use Windows
software. Software-selectable setup
parameters include logging rate,
start time, high/low alarm settings,
and temperature units (°C or °F).
Data can then be graphed, printed,
and exported to other applications
such as Excel. Each data logger
is supplied complete with a long-
life lithium battery. Built-in LED
indicators show data logger status.
OM-EL-USB Series data loggers are
protected against moisture to IP67
standards when the protective cap
is fitted.
