The ConductScience Total Hardness Test Paper (Model LH1014) provides semi-quantitative measurement of calcium and magnesium ions in water samples up to 1000 ppm. These colorimetric test strips employ a chromogenic reagent system that reacts specifically with divalent cations (Ca²⁺ and Mg²⁺) to produce a measurable color change, enabling rapid field assessment of water hardness levels.

The test strips utilize a competitive binding mechanism where hardness ions react with an immobilized indicator complex, producing color transitions that correlate with total hardness concentrations. This methodology supports water quality monitoring protocols in research laboratories, environmental studies, and analytical chemistry applications where rapid hardness screening is required.
