System
Overview
This
extractive
laser
gas
analysis
system
is
specifically
designed
for
high-dust
industrial
environments.
The
system
comprises
four
integrated
components:
sampling
probe,
pretreatment
unit,
control
unit,
and
gas
analysis
unit.
Utilizing
Tunable
Diode
Laser
Absorption
Spectroscopy
(TDLAS)
technology
with
transmissive
design,
it
provides
continuous,
real-time
gas
concentration
monitoring
to
optimize
gas
utilization,
enhance
energy
efficiency,
and
ensure
operational
safety.
