A very good and complete example of ballistic galvanometer or mirror galvanometer signed “J. Carpentier, Paris”, late 19th century.
A ballistic galvanometer is a type of sensitive galvanometer; commonly a mirror galvanometer. The first model was invented in 1882 by Desprez and d’Arsonval.
The present Carpentier’s exemple/type is described in 1895 in Dictionnaire d’électricité of Julien Lefèvre (see the last one picture).
The galvanometer is preserved in its original mahogany varnished case. It is a good and working condition.
Dimensions: height: 48 cm; base: 32x 17.5 cm
