Conductivity of Solutions Apparatus, Solution Conductometer 

For students educational use

The cover is designed to fit a clear glass tumbler. Light bulb, glass tumbler, and instructions sheets are provided. 

Lets your students actually observe increases and decreases in a liquid's conductivity. Consists of a molded socket on a pvc cover, provided with binding posts for connection of two wire cords. 

Two electrodes are internally connected to the lamp circuit. 

A plastic cover, cover is provided with a positive and negative banana plug terminal, positive terminal connected to a 0.3V/0.3A with a small lamp cathode, anode connected to a small lamp inserted under the lid of the copper wire; the negative terminal is connected with a mounted on the cover of carbon. 

The overall size is about 80*122mm in diameter.

Demonstration of the principle of electrolyte solution conductivity in teaching.

A glass with a diameter of 70mm and a high 80mm. 

In the experiment, into the amount of electrolyte solution in a glass, the glass will cover to cover, the copper wire and rod immersed in solution. 

With 4mm banana plug connection outside the DC3-6V power supply, small light bulbs, the electrolyte solution can be conductive.

Principle : when the electrolyte solution into DC, yin and yang ions in solution respectively to the anode and the cathode in the electrolytic reaction movement, electronic gain and loss, the loss of electrons at the anode, the electron on the cathode, forming the directional movement of the electrons, so the electrolyte solution can be conductive.

Note :

1, when doing the experiment, should pay attention to the glass gently;

2, the general solution of acid and alkali can be conductive, organic solution can not be conductive. 

Do experiments to confirm.

Product Dimensions : 4 x 3.5 x 3.5 inches ;
