reference electrode pseudo-reference electrode pseudo-reference electrodes CHMO:0002429 pseudoreference electrode https://orcid.org/0000-0001-5985-7429 2009-09-21T04:39:25Z An electrode through which no appreciable current is allowed to flow and is used to observe or control the potential at a working electrode. A pseudo-reference electrode, such as a Ag wire, fulfils the role of a reference electrode but the electrochemical processes allowing it to do so are not well understood, in contrast to a true reference electrode.
