About Water Hardness Testing:
Hardness is most commonly measured by titration with an EDTA solution. A titration involves adding small amounts of a solution to a water sample until the sample changes colour. You can titrate a sample for total hardness using a buret or hard water test kit. You can also measure calcium hardness separately from magnesium hardness by adjusting the pH and using different indicators. – Test strips are also available for measuring hardness. Using a hard water test strip, a color develops on the strip and the strip is matched to a chart.
The chart shows colors for concentrations of 0, 25, 50, 120, 250, and 425 ppm, or 1, 1.5, 3.7, 15, and 25 gpg.
Test strips should not be used when an exact hardness concentration is required!
