Innovative Device Makes Visualizing Conductivity Possible.
- Students can clearly see which solutions conduct electricity
- Reusable year after year
Observe increases and decreases in a liquids 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 kits glass tumbler filled with a designated liquid. Using the included light bulb, students can clearly see when a liquids conductivity is enough to illuminate the bulb. The small 3.7 V light is a safe alternative to other kits of this kind.
