Measuring principle
pH measurement
The pH value is a measure of the acid or base character of a medium. Depending on the pH value of the
medium, the electrode's membrane glass provides an electrochemical potential. This is the result of H +
ions selectively penetrating the outer layer of the membrane. As a result, an electrochemical boundary
layer forms here with an electric potential. An integrated Ag/AgCl reference system forms the required
reference electrode.
The transmitter converts the measured voltage into the corresponding pH value according to the
Nernst equation.
