ABSTRACT:
A conductimetric gas sensor consists of a ptfe body forming an electrolytic cell; two threaded silver electrodes screwed into the ptfe body and bridged by a layer of a hydrophilic gel in contact with an electrolyte in the cell; a reservoir for supplying deionized water to the cell, so that the volume of water between the electrodes is maintained; and a gas-permeable hydrophobic layer through which the hydrophilic gel can be exposed to the gas.
