Total Hardness Test Strips — Bulk Pack (50 units)

Bulk Pack — 50 units

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

Total hardness test strips provide rapid colorimetric determination of calcium and magnesium ions in water samples, with a measurement range extending to 1000 ppm as CaCO₃ equivalent. These strips utilize indicator chemistry that produces distinct color changes proportional to the combined concentration of Ca²⁺ and Mg²⁺ ions, the primary contributors to water hardness. The colorimetric response enables semi-quantitative assessment of total hardness without requiring laboratory instrumentation or complex sample preparation.

Water hardness assessment is fundamental to environmental monitoring, industrial process control, and laboratory water quality verification. Elevated hardness levels contribute to scale formation in equipment and piping systems, while insufficient hardness can result in corrosive water conditions that damage infrastructure. These test strips provide immediate feedback on hardness levels, enabling rapid decision-making in field and laboratory environments where timely water quality assessment is required.
