The concentration of sodium metal in a flow of mercury-sodium amalgam is measured by flowing an aqueous solution of sodium chloride through a conduit of electrically insulating material terminating with a porous septum or a capillary immersed in the flow of mercury-sodium amalgam, at a rate of at least 4 ml per hour and per cm.sup.2 of surface area of contact between the surface of the porous septum or the section of the capillary opening and the amalgam, and monitoring the electromotive force generated between said amalgam and a calomel or silver-silver chloride reference electrode located within said conduit and in contact with said solution.
