Laboratory for Emission Measurements FHNW

Our Offer

• We offer various measurement methods for emissions from thermal processes, including:
• Emission measurements in the combustion laboratory at the FHNW (Windisch) or externally on large plants. 
• Assessment and optimisation of combustion processes with regard to their emissions by means of online measurement of all important gaseous emissions to assess the combustion quality and online measurement of particle number, mean geometric diameter, respirable surface concentration (LDSA), mass concentration. 
• Measurement of the total dust mass concentration in accordance with the applicable Swiss and European standards. 
• Measurement of fine dust emissions (number and mass) in accordance with requirements for the Label Blue Angel for Wood-burning stoves (DE-UZ 212) 
• Measurement of the efficiency of dust reduction equipment  
• Measurement of the soot count
