Overview
The
KGD
WQ
511
Motor
Vehicle
Nitrogen
Oxides
Rapid
Detector
utilizes
ultraviolet
spectroscopy
technology
for
continuous,
real-time
measurement
of
NO
and
NO₂
emissions.
Equipped
with
Beidou
navigation
and
an
integrated
APP
software
platform,
this
detector
is
specifically
designed
for
measuring
nitrogen
oxide
concentrations
in
vehicle
exhaust
emissions
during
chassis
dynamometer
tests
or
actual
road
driving
conditions.
Key
Features
-
Direct
measurement
of
NO
and
NO₂
without
requiring
a
NOₓ
converter
-
Multi-stage
filtration
system
prevents
contamination
of
the
measurement
gas
chamber
-
Compact,
durable
construction
with
low
maintenance
requirements
-
Integrated
APP
software
platform
enables
convenient
remote
monitoring
