ANALYSIS OF RESULTS

gas species standard value (ppm) measured value (ppm) difference value maximum difference error
SO2 102 104 2 -4 0.8%
200 196 -4
499 501 2
NO 104 108 4 -7 1.4%
200 206 6
500 493 -7
NO2 116 112 -4 -9.7 1.94%
201.5 195 -6.5
501.7 493 -9.7
NH3 50 53 3 3 1.5%
200 199 -1
conclusion Accuracy error is less than 3%, which meets the design standard.
