Emission analyzer applications

Flue gas analysis in industrial installations often needs to be carried out in extreme conditions, involving high temperatures, high humidity or a high dust content in the flue gas, for example. Emission measurements are taken in resource- and energy-intensive processes, during which large quantities of emissions such as carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOX) or sulphur dioxide (SO2) are produced. With a number of exhaust gas probes, sensors and special options such as automatic dilution or Peltier gas preparation, the exhaust gas analyzers from Testo were specially developed for extreme demands.

Emission analyzer applications are included in industrial areas such as cogeneration plants, boiler plants, metal works, gas turbines, engines and mining. A Testo emission analyzer is designed to withstand the intense conditions of these environments and to help you take accurate readings throughout.

The emission analyzer from Testo offers you

  • Numerous measurement parameters: O2, CO, NO, NO2, SO2, CO2, H2S
  • Extensive selection of probes
  • Fast access to sensors and wearing parts
  • Measurement data management via software
