The reference electrode used in a half cell potential corrosion tester is selected based on the specific application and environment being tested. The PM8500 includes a copper/copper (Cu/CuSO4) reference electrode, but other electrodes such as the saturated calomel electrode (SCE) and the silver/silver chloride electrode (Ag/AgCl) can also be used.
