Bulk Pack — 50 units

Unit price: $13.99 each. Bulk pack savings for repeat-purchase lab consumables.

Water Hardness Test Strips provide rapid colorimetric determination of total hardness in water samples through measurement of calcium and magnesium ions. These test strips utilize indicator chemistry to produce color changes proportional to hardness concentration, with measurement range extending to 1000 ppm as CaCO3 equivalent.

The strips employ chelating agents that selectively bind calcium and magnesium ions, the primary contributors to water hardness, producing distinct color transitions that correlate with ion concentrations. This method enables field-portable assessment of water quality parameters critical for laboratory operations, equipment maintenance, and experimental protocols requiring controlled water specifications.
