About This Product
With its zero in the middle of the scale, a galvanometer shows not only that a small current is flowing but which way it flows. This DC coil galvanometer is offered in several centre-zero ranges, in milliamps and millivolts, for practical work in school and college labs where small currents and voltages have to be detected.
Frequently Asked Questions
Why does the scale have zero in the middle?
Centre-zero ranges such as 1-0-1mA let the pointer move either way, so the galvanometer shows the direction of a small current as well as its size.
