Conductivity Apparatus (Ingenhousz) and using the proof plane

and using the proof plane to investigate the distribution of charges on conductors

4 cylinders form the control panel)

Resistance Tube Included: The sliding rheostat comes with a resistant tube for added convenience and functionality

Clear Colorless: The solution exhibits a clear colorless appearance

They come in four masses

Conductivity Apparatus (Ingenhousz) and using the proof planeFive Rods, One each of Aluminum, Brass, Copper, Zinc and Iron, embedded along one side of a metal tank, size 150mm x 90mm x 100mm. Rates of Melting compared by placing wax on the ends of the different rods thus demonstrates rates of conductivity in the different metals. Premium Quality: Conductivity Apparatus is made of high grade construction all the way through, excellent build quality and proven reliability across the range. Designed for use in
