Abstract
Abstract An electrode assembly includes an elongated tubular support member to which is secured a coupling structure. An electrode structure is supported by the coupling structure and has a sensing surface that projects externally of the coupling structure. A housing structure has a selectively permeable membrane secured over an opening at one end so that a chamber is defined for receiving an electrolyte solution. The housing is connected to the coupling structure so that the exposed sensing surface of the electrode structure is disposed in the electrolyte structure with its sensing surface in contact and distorting the membrane structure. The housing and coupling structures have cooperating engaged locating surfaces that define the amount of permitted distortion of the membrane structure.
