Conductivity measurement is a versatile tool in process control. The measurement is simple, fast, and most advanced sensors require only a little maintenance. The measured conductivity reading can be used to make various assumptions on what is happening in the process. In some cases it is possible to develop a model to calculate concentration of the liquid. Concentration of pure liquids can be calculated when the conductivity and temperature is measured. The preset curves for various acids and bases are commercially available.

TEMPRATURE DEPENDENCE

The conductivity of a solution is highly temperature dependent, therefore it is important to either use a temperature compensated instrument, or calibrate the instrument at the same temperature as the solution being measured. Unlike metals, the conductivity of common electrolytes typically increases with increasing temperature.
The temperature compensation slope for most naturally occurring waters is about 2%/°C, however it can range between 1 and 3%/°C. The compensation slope for some common water solutions are listed in the table below.
