Gas Analyzer

Analyzer detecting free and dissolved gas in a papermaking process

The GAS-60 Gas Analyzer measures online both free air and dissolved gas by a sequential sampling and analysis technique. Paper, board and tissue making processes have become a lot more foamy due to excessive air mixed in from recycled furnishes, high turbulence operations and dissolved carbon dioxide gas released from calcium carbonate, commonly used as a filler and coating.
