Here are photos of the reference electrode, the billet, the bridge and a trial setup of a beaker ready for precipitation of a real emulsion. The reference electrode is immersed in its conditioning/storage solution, and the bridge is also immersed in its own gel/salt storage solution. The bridge is marked as to polarity and the salt that it is to be used with. These are two critical items in this measurement.

The making beaker in the 4th picture contains 2 inlet lines for salt and Silver, a temperature probe, the plated Silver billet, and the bridge. The bridge is a mockup in this but not in the other picture. The bridge is connected to the salt solution beaker on the far right which contains the reference electrode.

The pump is partially seen to the far left.

Both electrodes are connected to the VOM. It is then connected to a PC with a cable and data logging can be carried out as a function of time.


I'm slightly confused as how the bridge attaches to the meter,
