The H2S gas analyzer MONOCOLOR operates semi-continuously by the colorimetric measuring principle with a dry reaction on a reagent paper strip. The intensity of the reagent paper stain is proportional to the mean concentration of H2S and to the flowrate.This measuring principle is very selective, even in case of different sulfur compounds in the sample gas and allows the measurement of small H2S concentrations.

The MONOCOLOR is suitable for monitoring of hydrogen sulfide in natural gas, bio gas, landfill gas, coke oven gas, for ambient air and emission monitoring in desulfurization plants, the pulp & paper, chemical and petrochemical industry.
