Reaction Principle
a)CH2CI2+CrVI—> gaseous cleavage product
b) gaseous cleavage product +I2O5—>I2
Cross Sensitivity
Other halogenated hydrocarbons are indicated, but with different sensitivities. Carbon monoxide and petroleum hydrocarbons are indicated. It is impossible to measure methylene chloride in the presence of carbon monoxide and petroleum hydrocarbons.
Extension of the Measuring Range
Using 20strokes divide the reading by 2, the measuring range will be 50 to1,000 ppm methylene chloride.
