Application Range
Standard Measuring Range: 20 to 200 ppm
Number of Strokes n: 10
Time for Measurement: approx. 3 min
Standard Deviation: ± 10 to 15 %
Color Change: brown yellow -> white
Ambient Operating Conditions
Temperature: 0 to 40 °C
Absolute Humidity: < 30 mg H2O / L
Reaction Principle
SO2 + I2 + 2 H2O -> H2SO4 + 2 HI
Cross Sensitivity
Hydrogen sulfide is indicated, with the same sensitivity. It is impossible to measure sulfur dioxide in the presence of hydrogen sulfide. Nitrogen dioxide will shorten the reading.
Extension of the Measuring Range
Using n = 1+3 desorption strokes, multiply the reading by 10; the range of measurement is 200 - 2,000 ppm. The desorption strokes are to be taken
in clean air (i.e. free of sulfur dioxide) immediately following the single pump stroke.
