Nitrogen Oxides (NOx) Analyzer

The Model 200AH High Range NO/NO2/NOX Analyzer uses the field-proven chemiluminescent technique for monitoring high levels of oxides of nitrogen. User-selectable ranges of 5 ppm to 5000 ppm make it ideal for a wide variety of applications including CEM, stack testing, and process control. A choice of NO2-to-NO converters handles tough CEM and stack testing applications. Selectable measurement modes (NO only, NOx only, NO/NOx switching), auto ranging and remote range control let you set up the Model 200AH to your exact needs. The modular design offers top-mounted access to all subassemblies and has hinged front and rear panels to simplify module replacement. The modular, sealed ozone generator provides improved voltage coefficient, safety, and reliability. A standard permeation dryer on the ozone generator means there is no desiccant to replace. In addition, the excess ozone is removed by catalytic reaction, eliminating the need for charcoal (expendable) replacement.
