Conductivity Meter
A simple apparatus for testing the electrical conductivity of liquids. Connect the apparatus to the main supply and place the electrodes in the liquid used for testing. A strong conductor is a material that will let electric charges to flow through it very easy and therefore the bulb of conductivity meter glows brightly. The weak conductors allow electric charges to flow through it slowly and therefore the bulb of conductivity meter glows dimly. The bad conductors do not allow electric charges to flow through it and therefore the bulb of conductivity meter does not glow at all. Bulb provided is large and bright enough to be seen by the entire class. The conductivity meter includes a clamp on the back for attaching to a support stand. Instructions and appliance bulb are also included.
