Just run the test strip under water to evaluate your water hardness.

AQUADUR® water hardness test strips come in a wide variety of different gradations and packaging options for your individual needs. Single sealed test strips are for example available for promotion activities to inform customers about the necessity of water softeners.
Since we completely control the production process of our test strips in-house, we can cater to very specific or unique requests.

Water hardness test kits may use water hardness test tablets or paper test strips (see below).

After filling a glass with cold water from your bathroom sink, insert the test strip for several seconds and then remove it. Also, it’s important to note that you should not just stick the strip under running water, as this can provide inaccurate results. As the strip changes color, compare it to the color chart included in your kit. Each color on the chart corresponds to the hardness of your water, with results measured in grains per gallon (gpg).

Water Hardness Test Strips: Measure Water Hardness 0-30 gpg/500ppm

METHOD: In the presence of a green indicator the hardness ions Ca²? and Mg²? react with Titriplex® III to form a colorless, stable complex. The hardness ions that are present in excess relative to Titriplex® III react with the indicator to form a red complex. The reaction zones of the test strips, which are impregnated with differing amounts of Titriplex® III, thus assume a green to red color, depending on the hardness of the water sample. The total hardness is then measured semiquantitatively by visual comparison of the reaction zones with the color rows of a color scale.
