Conductivity is a sum parameter for the ion concentration of a measuring solution. The more salt, acid or base a solution contains, the higher its conductivity. The unit for conductivity is S/m, often also S/cm. Conductivity measurement is an electrochemical measurement. In the simplest case, a conductivity measuring cell consists of two electrodes of the same type, between which an alternating voltage is applied. The more ions the measuring solution contains, the greater the current flowing between the electrodes. The conductivity meter calculates the conductivity value on the basis of Ohm's law and taking into account the cell data.In practice, conductivity measurement is used, for example, to monitor systems, for quality control of ultrapure water or to determine the salinity of seawater.
