KGD-MQ-528
Integrated
Biogas
Analysis
System
The
KGD-MQ-528
Integrated
Biogas
Analysis
System
uses
non-dispersive
infrared
gas
analysis
technology
with
independent
intellectual
property
rights
and
long-life
electrochemical
sensing
technology.
It
can
continuously
monitor
the
volume
concentrations
of
gases
such
as
CH4,
CO2,
H2S,
and
O2
in
biogas
components
in
real-time
and
online.
The
system
can
be
optionally
equipped
with
a
pretreatment
unit
to
achieve
multi-channel
sampling
and
water-removal
functions,
adapting
to
various
biogas
working
conditions
on-site.
