What must be measured in conjunction with conductivity?

Conductivity is a measure of water's ability to conduct an electric current, which is influenced by the concentration of dissolved ions present in the water. When evaluating conductivity, it is essential to also measure temperature because the conductivity of a solution can vary significantly with changes in temperature. As the temperature increases, the conductivity typically increases as well, due to the higher mobility of ions in warmer water. Therefore, to obtain accurate and comparable conductivity readings, it is necessary to account for the temperature at which those measurements are taken. This ensures proper interpretation of the data, especially in contexts such as water quality assessment where temperature effects must be controlled.
