Online water hardness monitors titration to be able to determine the total hardness present in a sample, typically enabling optimisation of water softening processes such as ion exchange or reverse osmosis and enabling high quality production of products that are influenced by water hardness.
By performing an additional titration on the same sample, a water hardness analyser is capable of determining calcium hardness, magnesium hardness and total hardness in the same sample.
