Techniques {coulometry} can measure charge that has flowed, by weighing metal or gas produced by electrolysis. 1 Faraday = 96487 Coulomb = 1 mole of electrons.
Instruments {coulometer} can have silver anode and platinum cathode in silver perchlorate solution, in series with cell to test. Deposited silver weight indicates total charge that flowed.
Two platinum electrodes can be in iodine and potassium iodide solution. Titration with reducing agent finds iodide-concentration change.
Two platinum electrodes in potassium sulfate solution can produce hydrogen and oxygen gas.
