Potentiometric Sensors
The most common way to measure pH today is potentiometry—an electrochemical method that enables continuous, in-line monitoring. It is based on the direct relationship between electrical voltage and the pH of a solution.
In practice, the system measures the potential difference (voltage) between two electrodes: the measuring electrode and the reference electrode. This voltage is then used to determine the pH value.

Amperometric Sensors
Amperometric sensors are electrochemical devices that enable continuous, in-line monitoring by measuring changes in electrical current. They operate based on a chemical reaction that occurs at the sensor’s electrodes.
The typical design consists of two dissimilar electrodes—an anode and a cathode (e.g., silver/platinum or copper/gold). A fixed voltage is applied between the electrodes, causing a reaction at the working electrode (cathode).
The resulting flow of electrons generates an electric current, which is proportional to the concentration of the measured variable. This signal is then converted into a standard output by the sensor’s electronics and displayed by the controller.

Conductivity Sensors
Conductivity sensors measure the ability of a liquid to conduct electrical current, enabling continuous, in-line monitoring of ion concentration. Two common measurement methods are contacting and inductive (toroidal) conductivity.
Contacting conductivity uses electrodes in direct contact with the liquid and is best suited for cleaner solutions, where ion flow can be measured directly. Inductive conductivity, on the other hand, uses electromagnetic fields for non-contact measurement, making it ideal for corrosive or contaminated liquids.
The key difference lies in contact versus non-contact measurement and the underlying principle used (direct electrical current vs. electromagnetic induction), with inductive conductivity offering a more robust solution for challenging industrial applications.
