A galvanometer is an electromechanical measuring instrument for electric current. Early galvanometers were uncalibrated, but improved versions, called...

A mirror galvanometer is an ammeter that indicates it has sensed an electric current by deflecting a light beam with a mirror. The beam of light projected...

A ballistic galvanometer is a type of sensitive galvanometer; commonly a mirror galvanometer. Unlike a current-measuring galvanometer, the moving part...

A vibration galvanometer is a type of mirror galvanometer, usually with a coil suspended in the gap of a magnet or with a permanent magnet suspended in...

A string galvanometer is a sensitive fast-responding measuring instrument that uses a single fine filament of wire suspended in a strong magnetic field...

The thermo-galvanometer is an instrument for measuring small electric currents. It was invented by William Duddell about 1900. The following is a description...

than has ever been built before, under the trademarked name of Physio-galvanometer, or O-Meter. It has very little in common with the old type E-Meter....

In 1825 he developed the astatic galvanometer. Nobili's Galvanometer Schematics of Nobili's Galvanometer Galvanometer on display at MHS Geneva He worked...

from 1907. The first moving-pointer current-detecting device was the galvanometer in 1820. These were used to measure resistance and voltage by using a...

high-speed recorder used beams of ultraviolet light reflected off mirror galvanometers, directed at light-sensitive paper. The earliest instruments derived...

Beginning in 1901, Einthoven completed a series of prototypes of a string galvanometer. This device used a very thin filament of conductive wire passing between...

galvanometer was invented by the French engineer Clément Ader. In 1901, Einthoven, working in Leiden, the Netherlands, used the string galvanometer:...

When it is moved in or out of the large coil (B), its magnetic field induces a momentary voltage in the coil, which is detected by the galvanometer (G)....
