Conductivity measurement

The conductivity of a liquid depends on the concentration and activity of conducting ions in this liquid.



For concentration measurement the (inductive type) conductivity method is a low cost technology with the following limitations:
  • Activity and therefore conductivity strongly depends on temperature with up to 3 % per °C.
  • Conductivity measurement is effected by fouling, dirt, generation of complexes or hydrate covers.
  • Because of the physical background, the method is only suitable for inorganic liquids and solutions.
