The Analyzer
The new Model 9900 RM is a single
or multi-component gas analyzer
that can be used alone or as an
integrated part of a CEM (continuous
emissions monitoring) system. The
analyzer is 19” rack-mountable and
supports Modbus/RS485 and Ethernet
connectivity.
t The Model 9900 RM can be
configured to measure most gas
species that absorb in the UV.
Species typically measured directly
by the Model 9900RM include: SO2,
NO, NO2, H2S, COS, CS2, NH3, and
BTX. Up to five components can be
measured simultaneously making the
system very economical for multicomponent analysis needs.
t The simple and robust design of
the Model 9900RM is complemented
by powerful data processing
capabilities. The user-friendly
keyboard enables programming
of such variables as timing and
frequency of local zero and span

checks. Both analog and digital
outputs are available and serial
communications via Modbus
protocol. An optional paramagnetic
oxygen sensor can be included to
provide O2 corrected concentrations.
t When your requirement is for a
rugged, single or multi-gas analyzer,
free of interferences from water
and CO2, the Model 9900RM is your
answer.

The Measurement
The Western Research® Model
9900RM uses AMETEK’s proprietary
high resolution UV technology in
a dual beam, multiple wavelength
configuration. Resolution is better
than 0.02nm, while high intensity,
fixed-wavelength, line source lamps
emit low total power to reduce the
potential for sample photolysis. The
high resolution enables unparalleled
