    AQUADUR®  test strips

    Quick and easy determination of water hardness

    AQUADUR® test strips are for the quick and easy determination of water hardness. The convenient dip & read procedure and the clear colour changes from green to red ensure reliable results within seconds.

    The water hardness depends mainly on the amount of calcium and magnesium salts within the water. The total sum of these salts determines the actual water hardness. In the USA, water hardness is expressed in ppm (mg/l) CaCO3.
    Generally, water is often simply classified as “soft” or “hard” water. By and large, the following values apply to these terms:

    below 50 ppm CaCO3– very soft water
    50 – 120 ppm CaCO3– soft water
    120 – 240 ppm CaCO3 – medium hard water
    240 – 360 ppm CaCO3 – hard water
    above 360 ppm CaCO3– very hard water

    Water hardness plays an important role in everyday life and a wide variety of industries and applications. Hard water can even adversely affect taste and appearance of food.
    Hard water inhibits the lathering of soap, so more detergent has to be used in hard water in order to achieve the same cleaning results as in soft water. Additionally, hard water may cause calcification and can thus damage machinery, appliances, pipes or heating units.
    In many industries, water hardness is an important parameter in process control and has to be monitored constantly. Some examples of industries include the textile industry, dyeing factories, large scale laundries, water works and fish-farming and aquaculture

    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.

    AQUADUR® water hardness test strips are the ideal choice to quickly, easily and reliably determine water hardness.
