Abstract:
An electrochemical device for sensing fluid components, particularly gases, comprises a composition with which the component reacts to liberate elemental chlorine, bromine, fluorine or iodine. The chlorine, bromine, fluorine or iodine passes through a particulate layer of vitreous carbon and activates the positive electrode of a solid ionic electrolyte battery of the type: halogen/solid ionic electrolyte/metal electrode, whereby a voltage is generated across a measuring device, the voltage being a known measure of the concentration of the fluid component.
