The
HOBO
External
Temp/RH
data
logger
records
temperature
and
relative
humidity
in
an
indoor
environment
with

external
sensor.
Using
HOBOware®,
you
can
easily
configure
the
logger
alarm
to
trip

records
data
at
a

conditions.
The
logger
can
also
calculate
minimum,
maximum,
average,
and
standard
deviation
statistics.
This
compact
data
logger
has
a
built
‐
in
LCD
screen
to
monitor
the
current
temperature,
relative
humidity,
logging
status,
