Many ionic substances are easily measured by means of potentiometry using ion-selective electrodes (ISE). The potential between the ISE and a suitable reference electrode depends on the concentration of the ion-species to be measured. The most common ion-specific electrode is the pH-electrode.

This versatile measuring principle is used in the ISE-Analyser/Titrator to measure a variety of different parameters like halides, ammonium, sulphate, sulphide etc.

The reliable control of several critical parameters is required in many industrial processes. Also environmental regulations become a more and more important issue in waste water treatment and discharge. The Process Colorimetric Analyser PCA is a reliable analyser to monitor a variety of different inorganic and organic parameters.
