This 3V conductivity tester demonstrates the electrical properties of various liquids. The item consists of a molded plastic lamp socket mounted on a base with 2 binding posts for connecting a wire cord.

This handheld device provides a qualitative visual indicator of the conductivity of different solutions, acids or salts. Two brass probes can be touched to a solid substance, or immersed in a liquid, to show conductivity on green LEDs that range

Five different metal spokes, aluminum, steel, brass, copper and nickel, extend from a center hub, and are connected to a wooden handle. The hub is heated and the students watch as wax falls from each spoke in the order of conductivity.

Connector cords are useful in various electricity experiments, as well as in many apparatuses that require connections to power supplies. All of our connector cords are made of 18-gauge insulated wire.
