The working principle of the electrode 17: the conductive electrode is composed of a pair of metal electrodes with a fixed distance (L) and a fixed area (S). The electrode constant is defined as K ═ L/S. From the relationship of the resistance (R) to the resistivity (ρ): r ═ ρ × K. The resistance and the resistivity are inverted, that is, the conductance (G) and the conductivity (S) are obtained, and the relationship is K × G. In units of s/cm (or ms/cm,. mu.s/cm), where K is fixed by the electrode structure type and G is measured by the instrument. Conductivity is an important parameter characterizing the quality of a liquid, such as the purity of water, the content of impurities in the liquid, salinity, the concentration of the solution, etc.
The conductivity is measured by applying a signal source with fixed amplitude and fixed frequency to the conducting electrode to generate a current signal proportional to the conductivity of the solution to be measured. The conductivity at the temperature is obtained by the treatment of an instrument, in order to characterize the uniqueness of the solution to be measured, the conductivities at different temperatures are normalized to the conductivity at a certain temperature, and the conductivity value at 25 ℃ is displayed by the treatment of a temperature compensation program of the instrument.
