How can I insert a multimeter to measure current through a salt bridge? I want to measure more than just the pH change.
Doodle - I don't know what the resistance of the salt bridge is, but the simplest way to measure current through the bridge is to select a DC voltage such as 1.5 or 3.0 or 9 volts (all easily available through battery selection) and place in series with the multimeter and electrodes placed in each of the liquid containers connected by the salt bridge. You will be able to measure DC current directly on the multimeter.
