About This Product

A demonstration meter lets everyone in the room read the same pointer while the teacher builds a circuit at the front bench. Swapping the dial plate turns one instrument into an ammeter, voltmeter or galvanometer for Ohm's law, series and parallel circuits and induction demonstrations. The Demonstration Meter, Interscale can be supplied on export terms to Lesotho, Haiti, Iceland, Kuwait and Portugal.
