ABSTRACT:
Discloses is an improved device to facilitate detecting and measuring the concentration of gaseous hydrogen dissolved in a fluid. A polymeric membrane is in contact with the fluid and permeable to the hydrogen gas. An electrolyte is provided which is capable of producing oxidation of the hydrogen diffused through the membrane at a first electrode, and reduction of an oxygen-containing gas such as air, at a second electrode. The connection of a measuring device across the electrodes measures the intensity of the current generated by the electrochemical reaction of oxidation of the hydrogen gas. The electrodes and the electrolyte are mounted in an electrode mounting unit which includes a first, tightly sealed enclosure encased within a second, tightly sealed enclosure. The mounting unit is tightly mounted into a hollow housing. This housing is fixed to a base across one extremity of which extends the polymeric membrane.
