For products with specific properties. During the production process, it is necessary to adjust the pH so that the product meets the technical requirements. The pH of the product largely determines the properties of the final product.

To reduce production costs. If the output in the process at a certain pH increases, this means that production costs at this pH will be lower.

To reduce the risk to health and the environment. Some products at a certain pH can be dangerous. To assess the degree of hazard of substances, it is necessary first of all to measure the pH.

To comply with regulatory requirements. As stated above, some products may be hazardous. State bodies establish special rules to protect the public from any danger associated with the release of harmful substances.

To protect equipment. When in contact with reagents, production equipment may corrode if the pH is out of range. Corrosion shortens the life of the equipment, therefore, in order to avoid premature failure of the production line, the pH level should be monitored.

For scientific and research purposes. The pH level is an important characteristic that researchers use when studying chemical or biochemical processes.
