Hi Alvin, If I were to do a design with automatic shut-off in a constant current system I would monitor the voltage as it dropped and when it reached a predetermined level shut the powe off. This would require the use of some of the newer 8 pin microprocessors.
O n a constant voltage system then monitor the current as it increases. Both would require a fixed system of electrodes and stirring.
