KELMA - Model Monocolor1 N and Monocolor2 Ex -Gas Analyser for Hydrogen Sulfide

The H2S gas analyser 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 flow rate. This measuring principle allows the measurement of small H2S concentrations and is very selective, even in case of different sulfur compounds in the sample gas.
