The conductivity of a solution greatly changes depending on its temperature. Generally, the conductivity of a solution increases with temperature, but the degree of increase varies with the type and concentration of IONS. Therefore, it is necessary to keep the solution temperature CONSTANT when decisions are MADE using values of conductivity. Because it is difficult in practice to keep the solution temperature constant, the temperature is measured and converted into a reference temperature.

For industrial MEASUREMENTS, a temperature measurement device is built into the operation CIRCUIT for automatic conversion into the reference temperature. Temperature compensation is generally performed based on the temperature coefficient of dilute NaCl solution, but when the NaCl dilution solution is significantly different from the temperature coefficient, it is necessary to set the coefficient manually.
