A luggin probe is an instrument that determines the degree to which a metal material is likely to corrode. It is a small tube made of glass or plastic filled with electrolytes that serve as a reference electrode to a contacted surface that is called a working electrode.
A luggin probe is also known as a luggin capillary.
A luggin probe can also be used to change the potential of a working electrode material by minimizing the iR drop in the electrolytic cell formed when it interacts with the surface being examined. This capability makes luggin probes useful for preventing corrosion.
Synonyms
Luggin Capillary, Luggin Tip, Luggin-Haber Capillary
