VISOCOLOR® alpha Hardness (total)
Titrimetric determination of total hardness
Complexometric titration.
Reaction bases in accordance with DIN 38406 E3 and DIN 38409 H6.
The total hardness of water is based on its content of alkaline earth ions (calcium and magnesium ions). This content depends on the geological conditions the water encounters during its course and may vary widely. Knowledge of the total hardness is important for the use of water in industrial as well as municipal applications, e. g. in the household as wash water or as boiler feed water in industry.
