>>Principle

Since water contains various dissolved salts that exist in the form of ions, when electrodes are inserted into the water and an electric current is applied, the charged ions move in specific directions under the influence of the electric field. The anions in water migrate toward the anode, enabling the aqueous solution to conduct electricity. The ability of water to conduct electricity is termed ‌conductivity‌.

Conductivity is the reciprocal of resistivity and reflects the total dissolved salt content in water, serving as a critical indicator for assessing water quality. It reveals the concentration of electrolytes present in water. Depending on the concentration of electrolytes in an aqueous solution, the degree of electrical conduction varies. By measuring the conductivity of a solution, the solubility of electrolytes can be analyzed. This forms the fundamental analytical principle of conductivity meters.

Conductivity exhibits significant temperature dependence. For metals, conductivity decreases with rising temperatures, whereas for semiconductors, it increases with temperature. In solid semiconductors, doping levels can drastically alter conductivity—higher doping concentrations result in greater conductivity.

The conductivity of aqueous solutions depends on the concentration of dissolved salts or other chemical impurities that dissociate into electrolytes. The conductivity of a water sample serves as a key metric for measuring its salt content, ionic components, and impurity levels. Lower conductivity (higher resistivity) indicates purer water.

Water conductivity is often recorded as ‌specific conductance‌, which represents the conductivity of water at a standardized temperature of 25°C.
