For titration. Hardness in water is mainly due to the presence of calcium and magnesium ions and each contributes to the amount of total hardness. Monitoring and controlling hardness is instrumental in preventing scaling and corrosion. The reagent is then added under monitored conditions.

Hanna's extended description

Titration is used to find the concentration of an identified chemical in a solution (e.g., water).

In our standard Titration kits, there will be a Titrant solution that is added to the solution (e.g., water) to be tested to make it change colour.

During testing, when colour change is achieved, under careful conditions - usually using a burette – the reagent is added, drop by drop, until the solution turns clear. The user will then count how many drops of reagent were used to achieve complete colour dispersal. The number of drops used will determine the chemical concentration and results can be found in the manual included.

Hardness in water is mainly due to the presence of Calcium and Magnesium ions and each contributes to the amount of total hardness. Monitoring and controlling hardness is instrumental in order to prevent scaling and corrosion.

Water is categorised as very soft (0-70 mg/L), soft (70-150 mg/L), slightly hard (150-250 mg/L), moderately hard (250-320 mg/L), hard (320-420 mg/L) and very hard (420 mg/L and above), according to the hardness scale. Hanna kits cover all of these ranges.

Hanna offers the HI-3840-S, HI-3841-S and HI-3842-S chemical test kits packed in sachets offering a low cost alternative.
