    Conductivity is a parameter used to measure electrical properties of a solution. Conductivity measurements are used for applications such as in the production of ultrapure water or determining the salinity of saltwater. It is evaluated by making a direct measurement of the electrical resistance. The more ions in the solution, the greater the current which flows between the electrodes. The instrument measures the current and uses Ohm’s law to calculate first the conductance of the solution and then – by taking the cell data into account – the conductivity.
