In contrast to the probe pipe for portable analysers, where the most important are handiness and mobility, stationary probe is a neat and professional solution for extracting gas samples from single, immobile location. This probe was specially designed to work in anchored position, and is equipped with proper chimney adapter, that holds the probe steadily in the position. It may also be additionally equipped with cleanable filter and its cleaning option, what prolongs the maintenance intervals, or thermocouple for gas temperature measurement.


  • Stationary probe is a necessary piece of CEMS system.
  • Probe must be adjusted to the diameter of the exhaust duct, to the prevailing temperature and dust level.
  • Probe allows to extract gas sample and to initially clean it. For this purpose it may be equipped with sintered stainless steel filter.
  • Additionally, it is usually equipped with K-type thermocouple that allows to perform the measurement of gas temperature.
  • To ease the maintenance of the filter (its cleaning) the probe may also be equipped with the valve (manual or solenoid one) that channels connected compressed air to the probe's filter in order to clean it with a strong blow.
  • Probe may be connected to the heated hose that leads the sample to the gas dryer
  • Pictures below show examples of possible configurations of the stationary gas probe
