Description
The
Portable
Infrared
Natural
Gas
Calorific
Value
Analyzer
KGD
-
MQ
-
519
adopts
non-dispersive
infrared
(NDIR)
gas
analysis
technology
with
independent
intellectual
property
rights.
It
can
simultaneously
measure
the
calorific
values
of
coal-bed
methane
and
natural
gas,
as
well
as
the
volume
concentrations
of
multi-component
gases
such
as
CH₄
and
CₙHₘ.

Key
Features
-
Simultaneous
measurement:
Measures
gas
components
and
calorific
values
simultaneously,
replacing
combustion-type
calorific
value
meters.
-
High
accuracy:
NDIR
technology
eliminates
cross-interference
among
measured
gas
components.
-
Portable
design:
Suitable
for
both
field
industrial
measurement
and
laboratory
analysis.
-
Data
management:
Automatic
data
storage
with
query/delete
functions
and
multiple
interface
options.
-
Power
management:
Soft-start
power
switch
prevents
low-power
operation.
-
Low
operating
costs:
No
chemical
reagents
or
consumables
required.
