Fabrication, measuring methods and results in using silver/silver chloride and molybdenum/molybdenum oxide half cells to monitor corrosion currents are reported. The half cells are suggested as alternates to zinc bars to avoid destructive evolution of hydrogen. Potentials in 40 Wt% Na hydroxide and in Ca hydroxide at intervals up to 6 months are reported. Both types of solid state electrodes are subject to fabrication variables and physical abuse during pouring of concrete. Potentials of the Ag/Ag chloride vary 10% from calculated potentials, but are not believed sufficient to materially affect use in concrete.
