Electrochemical carbon meter

摘要

An electrochemical carbon meter is described which is especially useful for measuring the concentration of carbon in liquid sodium. The meter includes a carbon activity gas having a known ratio of carbon monoxide to carbon dioxide contained within a chamber as an intermediary between a diffusion membrane in contact with the sodium and an electrochemical cell. A calcium carbonate fixing compound is also located within the chamber for maintaining the concentration of carbon dioxide therein at a predetermined level. The chamber is fixed to the end of a probe tube which supports the same fully surrounded by liquid sodium to be maintained thereby at a uniform temperature.
