About This Product
A battery eliminator saves buying and replacing dry cells for every bench. Students pick the voltage their circuit needs and use the same supply for electromagnets, lamps, resistor networks and motor experiments in school and vocational physics. Educational Instrument can dispatch the Battery Eliminator to laboratories in Turkey, Somalia, Jordan, Portugal, Angola and Democratic Republic of the Congo.
