For accurate SO2 measurement a testo fluegas analyser must always be equipped with a SO2 and NO2 cell. NO2 has a negative impact on the SO2 reading by 110%. If the analyser measures NO2, it will automatically compensate for this. If not, then the SO2 reading might be far out depending on NO2 in the flue gas.
