This analog sensitive galvanometer is designed to measure weak current and small potential difference in DC circuit, and used for experiments such as wheatstone bridge, thermocouple, electro-magnetic induction, photoemission, and to expand ammeter range. This specific galvanometer measures from -35-0-35 milliamps.

Composed of plastic casing, analog indicating meter and input terminals, it is characterized by its compact and durable structure, stable performance, easy operation, and low cost. This meter is ideal for students in middle schools, vocational schools, and hobbyists.

The galvanometer is an analog electromechanical transducer that produces a rotary deflection of a pointer in response to electric current through its coil in a magnetic field.  When an electric current passes through the coil, the coil experiences a torque that is proportional to the current. The direction of change of the indicator indicates the polarity of the input current.
