By determining the total hardness level in natural water resources and wastewater, it provides important data for monitoring water quality and environmental sustainability.

By detecting calcium (Ca²⁺) and magnesium (Mg²⁺) ion concentrations in drinking water production, it helps determine whether the water meets quality standards.

Helps monitor calcium-magnesium hardness in process water and dye bath preparation, supporting control of dye uptake, spotting and scale-related risks.

Used in the Dyehouse Test Pack to check total hardness of process water. Helps evaluate hardness-related precipitation, staining, dye uptake variation and bath stability problems before production.
