Combustion analysis with Testo: professional and reliable.


Combustion gases contain, among others CO₂, CO, oxides or soot particles. These pollute the environment, have a negative effect on the climate and conceal numerous health risks for human beings.

Combustion analysis with professional combustion analyzers from Testo helps to make combustion processes more efficient, to optimize thermal processes, and above all, to reduce emissions.

  • Protection of the atmosphere thanks to as low a pollutant level as possible
  • The most efficient use of energy as possible
  • Adherence to prescribed pollutant levels per flue gas volume and energy loss
