摘要： A pH sensor has a core of an electrochemically inert insulating or semi-conductive material, and is coated with an electrically conductive, electrochemically sensitive coating. The preferred core is insulating and made of alumina, with a thin coating of iridium oxide deposited over at least a portion of the outer surface of the core. The coating is carried to a surface remote from the sensing surface and is used for making electrically conductive connections that lead to remote circuitry. The core is made in a form that can be supported and held in an insulating, electrochemically inert, deformable material that is sealed around the outer surface of the coating on the core to prevent leakage of chemicals being sensed. The body also permits sealing quite easily onto access ports on which the sensor housing is mounted. Various connections to the electrode coating can be made quite easily to provide for a unique sensor assembly.

摘要： A wick system for an electrochemical cell is provided to assure the connection between the electrodes of the cell. The wick system of the invention absorbs electrolyte and by capillary action provides a continuous electrolyte path between the electrodes. The wick may be in the form of a substantially flat piece extending in one plane for those cells having all electrodes positioned at one end thereof. Alternatively, the wick may be substantially tubular to extend from one end of a cylindrical electrolyte containing chamber to another, for a cell having electrodes positioned at each end thereof. Additionally, the wick may extend from one end of the cell to the other in a folded bellows-like form. In any of the forms, the wick system allows for a continuous operation of the cell, even with reduced electrolyte content, and regardless of the three-dimensional orientation of the cell, by absorbing electrolyte and maintaining electrolytic contact.
