Description
Direct-Insertion
Oxygen

KGD-MQ-512
Product
Introduction
The
KGD-MQ-512
Direct-Insertion
Oxygen
Analyzer
uses
a
high-precision
zirconia
sensor
and
has
an
integrated
direct-insertion
sampling
design.
It
can
quickly
and
accurately
conduct
on-line
detection
of
the
oxygen
content
in
flue
gas
generated
during
the
combustion
process
of
various
common
combustion
equipment.

This
product
is
widely
applied
in
industries
such
as
petrochemical,
power,
chemical,
steel,
metallurgy,
building
materials,
and
textile.
Through
real-time
on-line
detection
and
analysis,
it
monitors
the
residual
oxygen
content
in
flue
gas
generated
during
fuel
combustion.
By
understanding
the
combustion
degree
of
fuel
in
combustion
equipment,
it
guides
operators
to
adjust
combustion
control,
reduce
waste,
and
lower
energy
consumption,
ultimately
achieving
the
goals
of
energy
conservation,
emission
reduction,
and
environmental
protection.
The
KGD-MQ-512
Direct-Insertion
Oxygen
Analyzer
features
high
temperature
resistance,
high
accuracy,
long
service
life,
and
fast
response.
Product
Features
-
High-precision
zirconia
sensor
with
fast
response
and
long
service
life.
-
Adopts
a
new-type
sampling
probe
with
a
flow-guiding
gas-sampling
design,
which
can
automatically
introduce
the
sample
gas.
-
The
product
can
be
used
continuously
for
a
long
time
in
high-temperature
environments
within
700℃.
-
Protection
grade
IP65,
suitable
for
various
environments
and
resistant
to
harsh
weather.
-
The
oxygen
concentration
can
be
calibrated
on-site
with
air
or
standard
gas
to
ensure
measurement
accuracy.
-
Full-process
alarm
function.
When
the
oxygen
content
exceeds
the
alarm
set
value,
a
contact
alarm
signal
will
be
issued.
-
High-temperature
protection
for
important
components.
When
the
internal
temperature
of
the
meter
head
is
too
high,
a
temperature
alarm
prompt
will
be
issued.
-
Adopts
two
signal
transmission
methods,
RS485
and
4-20mA,
to
meet
various
on-site
working
conditions.
