Hardness (total) Test Background:
The total hardness of water is based on its content of alkaline earth ions (calcium and magnesium ions). This content depends on the geological conditions the water encounters during its course and may vary widely. Knowledge of the total hardness is important for the use of water in industrial as well as municipal applications, e. g. in the household as wash water or as boiler feed water in industry. Copper(II) ions can delay or (in higher concentrations) even block the colour change of the indicator. For this reason allow enough water to run through copper pipes prior to sampling.
VISOCOLOR ECO Range:
VISOCOLOR ECO presents a product group of colorimetric and titrimetric test kits which avoids hazardous substances wherever possible. With VISOCOLOR ECO even water constituents with low limiting values can be determined with sufficient accuracy. All VISOCOLOR ECO test kits are packed in an environment-friendly box and contain easy to understand instructions in 6 languages. Many of the colorimetric tests can also be used in conjunction with the PF-3 and PF-12 photometers for photometric evaluation of results.
