Meaning and Definition
A sensitive instrument that measures minute electric currents by the heat they generate, causing the expansion of a wire which moves a needle.
A historical scientific device from the 19th and early 20th centuries combining principles of thermoelectricity and galvanometry, used primarily in telegraphy and early electrical research to detect and measure very small direct currents.

FAQ
Frequently Asked Questions
No, it is a historical instrument made obsolete by more robust, accurate, and faster electronic amplifiers and digital multimeters.
A standard galvanometer measures current via magnetic forces (a coil in a magnetic field). A thermogalvanometer uses the heating effect of the current to cause expansion, which mechanically moves a needle.
The principle was developed by several 19th-century scientists, including William Thomson (Lord Kelvin), who created highly sensitive versions for telegraphy.
You are unlikely to find new ones. They occasionally appear in auctions or sales of antique scientific instruments for collectors and museums.

Thermogalvanometer is usually technical, historical, scientific in register.
Thermogalvanometer: in British English it is pronounced /ˌθɜː.məʊ.ˌɡæl.və.ˈnɒm.ɪ.tə/, and in American English it is pronounced /ˌθɝː.moʊ.ˌɡæl.və.ˈnɑː.mə.t̬ɚ/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
Think: THERMO (heat) + GALVANO (electricity, from Galvani) + METER (measurer) = a meter that measures electric current by the heat it produces.
Conceptual Metaphor
A translator: It translates the invisible flow of electricity into the visible movement of a needle via the intermediate language of heat.
