MAINTENANCE
Calibration
The
ES
SAN
‐
01
comes
pre
‐
calibrated
from
the
factory.
However,
the
CO2
sensor
should
be
calibrated
at
least
once
a
year,
or
as
described
in
your
company’s
safety
procedures.
You
can
perform
the
calibration
yourself,
or
you
can
return
it
to
CO2Meter
for
factory
calibration
at
a
nominal
fee.
CO2
calibration
requires
100%
nitrogen
calibration
gas,
a
flow
regulator
and
flexible
tubing.
These
can
easily
be
obtained
online,
or
by
calling
CO2Meter
at
(386)
872
‐
7665.
The
temperature
and
humidity
sensors
do
not
require
calibration,
and
should
remain
accurate
for
the
life
of
your
unit.
