1. An ion selective electrode comprising:

  • a conductive electrode body having an essentially planar first surface A1 with an outer edge;

    an insulating substrate supporting the electrode body and having an essentially planar first surface which surrounds and is essentially coplanar with the first surface of the electrode body; and

    a convex dome-shaped ion selective membrane over the first surfaces of the electrode body and the insulating substrate;

    the membrane covering an area A2 which is greater than the area of the first surface of the electrode body and the membrane having an outer edge which is spaced laterally from and which is essentially coplanar with the outer edge of the first surface of the electrode body.
