The Topaze 32M analyzer uses the Chemiluminescence technique for measuring NO/NOx. In NO mode, it relies on the reaction between ozone and nitric oxide, producing light proportional to the NO quantity. For total NOx, the sample is converted to NO before measurement.

The analyzer features a heated inlet capillary block and measurement chamber to prevent condensation. It is microprocessor-controlled with complete gas data, diagnostics, alarms, and calibration settings accessible via keypad or remotely. Ranges can be selected automatically or manually, with automatic calibration options.
