Description

Observe increases and decreases
in a liquid’s conductivity with
this innovative apparatus and
demonstration. A molded socket
on a PVC cover is provided with binding posts for connecting two wire cords. Two
electrodes are also internally connected to the lamp
circuit. Fit the molded cover over the kit’s glass
tumbler filled with a designated liquid. Using the
included light bulb, students can clearly see when a
liquid’s conductivity is enough to illuminate the bulb.
The small 3.7V light is a safe alternative to other kits of
this kind. Includes instructions.
