Introduction
The
KGD-MQ-508
In-situ
Laser
Process
Gas
Analyzer
is
a
high-performance
optical
analysis
instrument
based
on
Tunable
Diode
Laser
Absorption
Spectroscopy
(TDLAS)
technology.
It
does
not
require
a
sampling
pretreatment
system
and
can
measure
in-situ
gas
concentration
in
harsh
environments
such
as
high
temperature,
high
dust,
and
high
corrosion.
Product
Features
-
Using
TDLAS
technology,
the
measured
gas
is
not
affected
by
cross-interference
from
background
gases
-
Single-ended
opening,
no
need
for
optical
alignment;
the
plug-in
design
greatly
simplifies
installation
and
debugging
-
No
sampling
pretreatment
system
required,
enabling
real-time
and
rapid
measurement
-
Built-in
standard
gas
reference
module
for
dynamic
compensation,
locking
the
absorption
spectral
line
in
real-time
without
being
affected
by
temperature,
pressure,
and
environmental
changes
-
Suitable
for
harsh
industrial
environments,
resistant
to
chemical
corrosion,
high
dust,
and
high
moisture
