1. A rotational test electrode assembly for use in a corrosive fluid environment comprising:
a) a generally cylindrical heat and electrically conductive member having an annular portion, a solid portion, and mounting
means for attaching a rotational electrode in close-fitting heat and electrically conductive relation, the electrode being
selected from the group consisting of cylindrical and disk electrodes;
b) a heating device positioned inside of the annular portion and in heat exchanging relation with the solid portion of the
conductive member;
c) a corrosion resistant external protective member that surrounds a portion of the heat conductive member in close-fitting
relationship;
d) electrical terminal means for receiving a plurality of external electrical connectors that is mounted on the protective
member opposite the portion of the conductive member on which the rotational electrode is mounted; and
e) driving means to rotate the rotational test electrode assembly.
