Abstract
An improved sensor apparatus of a kind that positions a semi-permeable membrane adjacent to an electrode assembly, for measuring a predetermined parameter, e.g., glucose concentration, of an adjacent fluid sample. A special compressible ring serves a first function of tensioning the membrane so that it is maintained in intimate contact with the electrode assembly, and it further serves a second function of sealing the fluid sample from the external environment.
