Dissolved
oxygen, Usually
recorded
as
DO.
Expressed
in
milligrams
of
oxygen
per
liter
of
water,
mg/L.
The
content
of
dissolved
oxygen
in
water
is
closely
related
to
the
partial
pressure
of
oxygen
in
the
air
and
the
temperature
of
water.
The
lower
the
water
temperature,
the
higher
the
dissolved
oxygen
content
in
the
water.
Dissolved oxygen value is a basis for studying the self-purification ability of water. The dissolved oxygen in the water is consumed, and it takes a short time to restore to the initial state, indicating that the water body has strong self-purification ability, or the water body is not seriously polluted. Otherwise, it means that the water body is seriously polluted, the self-purification ability is weak, or even loses the self-purification ability.

FAQ
1.
Which
sensors
can
be
connected
to
your
dissolved
oxygen
controller?
A:
The
dissolved
oxygen
meter
can
be
compatible
with
DRFN
digital
dissolved
oxygen
sensors
including
fluorescence
and
polarography.
2.
How
does
your
DO
controller
collect
sensor
data?
A:
The
connected
sensor
uploads
the
detected
data
in
a
special
encrypted
communication
method
to
ensure
that
the
DUC
controller
can
collect
high-precision
data
more
stably
