CEM/Humox

The CEM/Humox Moisture in Flue Gas Analyzer isdesigned to measure net oxygen and moisturecontent in flue gas and process applications. TheO2 and moisture data is used to correct emissions,assure product quality, or minimize stack corro-sion. The analyzer indicates moisture, oxygen-wetand oxygen-dry concentrations in percent byvolume.
