Definition - What does Luggin Capillary mean?
A Luggin capillary is a device used in electrochemistry to transmit a high level of current density on the surface of an electrode in attempts to determine the potential measurement of the electrode.
Corrosionpedia explains Luggin Capillary
A Luggin capillary is an ideal method used to reduce the distance between the sensor tip of a reference electrode to that of the working electrode. This effectively reduces the IR drop that is often undercompensated.
