    The JBL KH test set is an easy-to-use quick test for determining the carbonate hardness, or rather, the acid binding capacity in fresh and marine water.


    • Colour change from blue to yellow
    • The number of used drops = level of carbonate hardness
    • For this reason this test does NOT require a color scale
    • Includes syringe for simple measurement of the amount of water

    Leicht anzuwenden und gut ablesbar. Bis jetzt hat der Test mich noch nie enttäuscht und mir anscheinend auch gute Ergebnisse geliefert.
