Application Range
Standard Measuring Range: 2 to 60 ppm
Number of Strokes (n): 20
Time for Measurement: approx 8 min
Standard Deviation: ±10 to 15%
Color Change: white -› brown grey
Ambient Operating Conditions
Temperature: 0 to 40 °C

Reaction Principle
C6H6 + I2O5 + H2SO4 -> I2
Cross Sensitivity
Alkyl benzenes such as toluene or xylene up to a concentration of
200 ppm do not affect the indication. It is impossible to measure
benzene in the presence of petroleum hydrocarbons and carbon
monoxide.
