ABSTRACT:
A novel electrochemical cell monitoring apparatus for a caustic-chlorine electrolyzer, which includes a voltmeter, a standard calomel reference electrode, a flexible conduit for cell bath, preferably of multilayer construction, and a conduit support body placed between electrode walls to prevent crimping of the conduit when the walls of the electrolyzer are pressed together or dislocation during operation, and the method of monitoring a selected electrochemical cell which includes connecting an electrode of the selected cell and the standard reference electrode to the voltmeter, providing cell bath from the electrode of the selected cell through the conduit to the liquid junction of the standard reference electrode, operating the electrolyzer and reading the voltage on the voltmeter to compare with a predetermined standard voltage.
