Application No. 08/714,914
container body when they are jointly rotated,
said means not including use of any cement or
adhesive or any incorporation of the
fluoride-sensing crystal into a cohesive
unitary solid from which it can not be
removed intact without dividing all parts of
the unitary solid that do not consist of the
fluoride-sensing crystal into at least two
separate pieces;
(E) means for dividing the central cavity of the
primary container body so as to constitue,
jointly with the primary container body, the
fluoride-sensing crystal, and at least one of
the first and second elastomeric gaskets,
boundaries of a liquid- and vapor-tight
portion of the central cavity of the primary
container body;
(F) a volume of a first liquid ionic solution of
known composition and concentration confined
within said substantially liquid- and vapor-
tight portion of the central cavity of the
primary container body and in physical
contact with the fluoride-sensing crystal;
(G) a first reference electrode enclosed within
said substantially liquid- and vapor-tight
portion of the central cavity of the primary
container body, said first reference
electrode including a metallic electrical
conductor that is in physical contact with
the first liquid ionic solution but is not in
physical contact with the fluoride-sensing
crystal; and
(H) an electrically conducting lead component
that is in physical contact with both the
metallic electrical conductor part of the
first reference electrode and a point outside
