The sensor types with cell constants k=1 cm-1 are used in numerous kinds of water without film-forming components up to 20 mS/cm. Both sensors have a large bore for optimal resistance to fouling processes and when properly installed, the flow will keep the sensor clean preventing measuring errors. Parra, L.; Sendra, S.; Ortuo, V.M. Conductive, 2 electrodes. The downside of the inductive method is that the solution must have a high enough level of conductivity to interact with the electric field given off by the cells. The established and mostly used technology for inductive conductivity measurements is the transformer-type sensor, which uses two toroidal coils.
