An instrument combining galvanic current measurement with temperature measurement; a device using thermoelectric effects to measure temperature via electrical current.
From galvano- (galvanism) + thermometer (from Greek therme, heat + metron, measure). Developed as scientists discovered that temperature changes produced electrical effects.
The galvanothermometer was based on the Seebeck effect—when you heat a junction of two different metals, they generate electricity, allowing you to measure temperature just by measuring that electrical current instead of using mercury.
