ABSTRACT:
The moisture content of a gaseous mixture containing oxygen and the amount of other constituent gases in said mixture are determined by measuring, with an electrochemical cell, the ratio of oxygen partial pressures of a sample flow of said mixture and a comparison flow of a mixture of gases differing from said sample flow only by the reduction of the moisture content to a known level or, if moisture is not present, the reduction to a known level of the content of such other gaseous constituent. Also, provision is made to permit determining the amount of free oxygen in said gaseous mixture.
