pH measurement is one of the most important online analysis methods in the chemical industry.
The monitoring, accuracy and maintenance of the pH value in the production plants is a guarantee for optimised product yields.

Very high demands are made on a measuring point in the food and pharmaceutical industries with regard to hygiene and cleanability. Endress+Hauser offers a wide range of special pH sensors for this purpose which are characterised by optimum cleanability, a high number of CIP and SIP cycles and the possibility of autoclaving.

The treatment of drinking water or wastewater always involves monitoring regulated processes. As a result, the pH value is one of the most important measured variables in all stages of the process as both a value determining the quality of the water and as a controlled variable which has a direct effect on the economic efficiency of the plant.

pH measurement in a power plant protects pipes and turbines of corrosion and has a direct effect on the economic efficiency of the plant. pH in gas washing applications controls the cleanliness of the discharged air and the efficiency of the gypsum production as by-product.
