Problems in measuring sulfur dioxide at the fan outlet
Thread Content
Recent measurements of sulfur dioxide emissions from the fans showed that the concentration was around 10%. After calibrating the gas concentration meter with sulfur dioxide standard gas, the results obtained through iodometric analysis do not match those shown by the meter; the analysis values are consistently too low. What could be the reason?
Hehe, is there no one to help solve it?
Find out the cause of the error: whether it is due to factors, analysis methods, or the reagents. Just provide symptomatic treatment.
