Total Hardness drop test kits with color-change detection for Water Softening, boilers, cooling systems, swimming pools, and wastewater treatment. Low hardness water. Mains water.

Hardness test kit for mains water (single bottle) 1 drop = 1°F

Ref: ORMCD1003
Range: 1 to 60°F
Number of tests: 20 to 40

The dropper titration method changes the color of the sample from red to blue at the equivalence point. The number of drops needed for the color to change represents the hardness concentration.

Total Hardness (TH) of water is expressed in French degrees (°f), where 1°F corresponds to 10 mg of CaCO₃/L

FAQ Hardness test kit for mains water (single bottle) 1 drop = 1°F

Total hardness is the sum of carbonate and non-carbonate hardness. Carbonate hardness, due to calcium and magnesium bicarbonate, is sometimes called temporary hardness, and can be removed by boiling. Noncarbonate hardness, due to calcium and magnesium nitrates, chlorides, and sulfates, is also known as permanent hardness.

Hardness monitoring is vital in many fields, including the food industry, cooling systems, boilers, and power generation. Water of a specific quality, with controlled hardness concentrations, is essential to ensure optimal efficiency of machinery and to extend its useful life. Specific applications include preventing scaling in water heaters, managing boiler water to prevent corrosion, and optimizing the performance of softening systems to eliminate the adverse effects of hardness on industrial processes.

Hardness measures the concentration of calcium and magnesium ions, while alkalinity measures the ability of a solution to neutralize acids. Although related, hardness focuses on calcium and magnesium, while alkalinity includes the contribution of carbonate, bicarbonate, and hydroxide ions.
