Corrosion testing apparatus

摘要

A rotational test electrode assembly for use in a corrosive fluid environment as shown in FIG. 1 that includes a generally cylindrical heat and electrically conductive member ( 110 ) having an annular portion ( 112 ) and a solid portion ( 114 ): a heating device ( 130 ) positioned inside of the annular portion and in heat exchanging relation with the solid portion of the conductive member; a corrosion resistant external protective member ( 140 ) that surrounds a portion of the heat conductive member in close-fitting relationship; mounting means for attaching a rotational electrode ( 150 ) in close fitting heat and electrically conductive relation, the electrode being selected from the group consisting of cylindrical and disk electrodes; and an electrical connector 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.
