Models 200EH/200EM
Chemiluminescene High &
Medium Range NO/NO2/NOX
Analyzers
The Models 200EH and 200EM use the proven chemiluminescence measurement
principle, coupled with state-of-the-art microprocessor technology for
monitoring high and medium levels of nitrogen oxides. User-selectable
analog output ranges and a linear response over the entire measurement
range make them ideal for a
wide variety of applications, including extractive and dilution CEM,
stack testing, and process control.
A choice of NO2 converters handles tough CEM and
stack testing as well
as combustion turbine startup and continuous operation applications.
Selectable measurement modes (NOX only, NO only,
NO/NOX switching),
auto ranging (single range, dual range, auto-range, independent ranges,
remote range control) enables to match the Models 200EH or 200EM to
your needs.
Modular instrument design offers top-mounted, quick access to all
subassemblies and hinged front and rear panels to simplify module
replacement and maintenance. A standard permeation dryer on the ozone
generator provides dry air and excess ozone is removed by catalytic
reaction, both eliminating the need for expendables.
All instruments in the Teledyne-API Model “E”-
Series include built-in
data acquisition capability with internal memory. This allows logging
of multiple parameters in different predefined or customized data
channels including averaged or instantaneous concentration values,
calibration data, and operating parameters such as pressures and flow
rates.
Stored data are easily retrieved through the RS-232 port via APICOM or
from the front panel, allowing predictive diagnostics and enhanced data
analysis by tracking parameter trends. The Models 200EH and 200EM
combine rugged construction, light weight, ease of use,
powerful diagnostics and outstanding performance for high and medium
range applications.
