Overview
The
KGD-WQ-512
Vehicle
Emission
Gas
Analyzer
(Diesel
Vehicle)
detects
NO
concentration
using
high-precision
micro-flow
infrared
dual-gas-chamber
sensor
technology
with
patented
design
(PCT/CN2018100767).
It
measures
NO₂
via
non-dispersive
ultraviolet
(NDUV)
absorption
without
requiring
a
NOₓ
converter,
and
simultaneously
detects
CO₂
concentration
using
non-dispersive
infrared
(NDIR)
absorption
technology.
