£ 20.00
These Philip Harris Galvanometers with shunts and resistor loads are used to measure current change. A galvanometer is an electromechanical instrument used for detecting and indicating electric current. It works as an actuator, by producing a rotary deflection, in response to electric current flowing through a coil in a constant magnetic field.
