Product
Introduction
The
KGD
-
MQ
-
531
Biogas
Analyzer
(Smart
Portable
Type)
features
a
portable
design.
It
adopts
non-dispersive
infrared
gas
analysis
technology
with
independent
intellectual
property
rights
and
long-life
electrochemical
sensing
technology.
It
can
simultaneously
measure
the
volume
concentrations
of
gases
such
as
CH4,
CO2,
H2S,
and
O2
in
biogas
components
online.
While
inheriting
the
advantages
of
the
previous-generation
product
such
as
high
accuracy
and
no
consumables,
its
volume
has
been
reduced
by
75%
and
its
weight
by
60%,
making
it
outstandingly
compact
and
more
convenient
to
carry.

Product
Features
-
Portable
Body
Design:
Easy
to
carry,
it
can
meet
the
needs
of
both
on-site
industrial
measurement
and
laboratory
air-bag
sampling
analysis.
-
High
Measurement
Accuracy:
With
a
modular
sensor
design,
it
can
simultaneously
measure
the
volume
concentrations
of
gases
such
as
CH4,
CO2,
H2S,
and
O2
in
biogas
components
online.
CO
and
H2
sensors
can
be
extended,
and
there
is
no
cross-interference
among
multi-component
measured
gases.
-
Stable
Working
Performance:
The
sensor
adopts
a
dual-channel
design,
which
is
highly
stable.
It
has
a
self-diagnosis
function
and
can
check
the
sensor
status
online.
-
Intelligent
Battery
Management:
Equipped
with
a
soft-start
power
switch
and
intelligent
battery
management
to
prevent
the
instrument
from
operating
under
low-battery
conditions.
-
Simple
Data
Management:
Automatically
stores
measurement
data,
with
query
and
deletion
functions.
Data
can
be
transmitted
to
the
superior
centralized
control
system
through
multiple
interfaces.
-
Low
Cost
of
Use:
Compared
with
gas
analysis
technologies
such
as
Orsat
and
chromatography,
the
measurement
process
does
not
require
disassembly
and
installation,
nor
does
it
consume
chemical
reagents.
It
is
simple
to
operate
and
has
no
consumables.
-
Can
collect
gas
flow
rate
(requires
a
handheld
flow
meter
to
be
configured).
-
Has
a
Bluetooth
function,
enabling
the
uploaded
collection
data
to
be
displayed
on
the
APP.
