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. 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. Response Time Adjustable from 1.5 to 10 secs. 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.
