Nissan A32-EL power supply circuit diagram
The device contains a source of current and two electrodes that are placed in the sample. As the current passes through the solution, ions in the solution move and create a conductive path. The more ions present, the higher the conductivity, and the greater the voltage difference measured between the electrodes.
