An electrolytic detector, or liquid barretter, is a type of detector (demodulator) used in early radio receivers. It was first used by Canadian radio researcher Reginald Fessenden in 1903, and used until about 1913, after which it was superseded by crystal detectors and vacuum tube detectors such as the Fleming valve and Audion (triode).
