Galvanometer

Galvanometer – Electrical Current Measuring Instrument

The Galvanometer by ELMO Agencies is a precision electrical measuring instrument used to detect and measure very small electric currents. It operates on the principle of electromagnetic interaction between a magnetic field and a current-carrying conductor, causing a pointer to deflect in proportion to the current flowing through the circuit.

Widely used in physics laboratories, educational institutions, research centers, and scientific experiments, the galvanometer is an essential instrument for studying electrical and magnetic phenomena.

What Is a Galvanometer?

A Galvanometer is an electromechanical device designed to detect and measure small electric currents in a circuit. It indicates both the presence and direction of current flow through the movement of a needle or pointer across a calibrated scale.

The instrument plays a vital role in electrical experiments, circuit analysis, and scientific research involving current measurement.
