Abstract: A CORROSION PROBE ASSEMBLY FOR MEASURING CORROSION RATES OF METALLIC ELECTRODES IN CORRODANT ELECTROLYTE SOLUTIONS. THE PROBE IS DESIGNED FOR SIMPLICITY OF CONSTRUCTION AND SERVICEABILITY, AND COMPRISES A REFERENCE ELECTRODE BENT AT SUBSTANTIALLY A RIGH ANGLE TO BRING IT INTO CLOSE PROXIMITY WITH A TEST ELECTRODE. THIS ELECTRODE DESIGN PERMITS A MINIMUM SOLUTION IR DROP IN THE CORRODANT ELECTROLYTE, AND IT ALLOWS ACCURATE CORROSION RATE MEASUREMENTS IN ELECTROLYTES OF HIGH RESISTIVITY.
