Fully automatic water analysis

The determination of the following physical and chemical parameters is necessary for evaluating water quality: electrical conductivity, pH value, p and m value (alkalinity), chloride content, calcium and magnesium hardness, total hardness and fluoride content. This Application Bulletin describes how to determine the above mentioned parameters in a single analytical run.

Additional important parameters for water analysis include the permanganate index (PMI) and the chemical oxygen demand (COD). This Bulletin therefore also describes the fully automatic determination of PMI according to DIN EN ISO 8467 and of COD according to DIN 38409.
