ABSTRACT:
A system for the continuous analysis of furnace gasses for carbon dioxide and oxygen levels is disclosed. Materials which would be detrimental to the measuring instruments are removed before the gasses reach the measuring instruments. In particular, moisture content is removed by condensation at temperatures near freezing whereafter the gas is permitted to continuously warm up as it goes through the measuring instruments so that no condensation takes place in the measuring instruments.
