API Model 200AH Oxides of Nitrogen Analyzer
The API Model 200AH NO/NO2/NOx analyzer
uses the analytical technique of chemiluminescence.
The instrument is microprocessor and can simultaneously output NO,NO2,
and NOx concentrations.
The has an internal high temperature convertor and calculates NO2
to
NO conversion efficiency
real-time. The provided vacuum pump provides vacuum for the reaction
chamber and filtered air
for ozone generation. Ranges are user defined from 5 to 5,000 ppm.

API Model 252 Oxides of Nitrogen Analyzers
The API Model 252 NOx analyzer uses the analytical technique
of chemiluminescence. The instrument is coupled with an internal molybdenum
convertor and can be coupled with an
external stainless steel convertor. The vacuum pump provides vacuum
for the reaction chamber
and filtered air for ozone generation. Three selectable ranges can
be chosen. Dilution - Extractive
Range Instruments are available.

California Analytical Model 300CLD Oxides of
Nitrogen Analyzer
The California Analytical Model 300CLD NO / NO2 / NOx analyzer uses
the analytical technique of chemiluminescence. The instrument, unlike most
other NOx analyzers, requires positive pressure
for the sample and is supplied with a positive pressure pump. Response
times are extremely fast yet an external air supply is needed for ozone
generation. Multiple ranges are available from 100 ppm to 10,000 ppm.

Service Note:
The California Analytical NOx Analyzer requires the use of
an external air source for ozone generation. If you expect NOx concentrations
above 2,000 ppm, an oxygen source is needed for proper operation.
