Test the conductivity of liquids in a test tube or narrow beaker.
· Can test conductivity of solids as well.
· Two stainless steel wires, connected to the globe, will fit into the test tube.
· Overall length: 140mm (approx.); Plate size: 80mm x 60mm x 2mm (approx.)

NOTE: Power source such as 2 x AA batteries and suitable battery holder is required (3 x AA can also be used with a suitable battery holder - depending on conductivity/resistance of item being tested).
A single 1.5V battery does not supply adequate current for the globe to register the conductivity of liquids.

{This apparatus can be used in conjunction with the 2 way component holders (PA0875-001) which has 2 x banana sockets & 2 x connectors to allow connections to be made to small or fragile components by standard 4mm banana plugs}.
