    Easy-to-use water hardness test strips. It is enough to dip the strip for a few seconds to read the value of the measurement.

    The strip contains 5 squares: each means 5 German degrees 0/5/10/15/20/25

    The color of the squares during the measurement indicates the water hardness: from 0 to 25 German degrees

    German degrees ( °n or °d) - 1°n = 10.00 mg CaO in 1 liter of water and 1°n = 17.86 mg CaCO3 in 1 liter of water

    The typical hardness of tap water is approx. 10°n. Water below 3°n is considered soft and water above 30°n is considered hard.

    very soft: <75 mg CaCO3 / dm3
    soft: 75–150 mg CaCO3 / dm3
    medium hard: 150–300 mg CaCO3 / dm3
    hard: 300–500 mg CaCO3 / dm3
    very hard:> 500 mg CaCO3 / dm3
