Makes it easy to monitor the carbonate hardness in fresh and salt water

  • Directions for use:

    Directions for use: Shake reagent bottle well before using!
    1. Rinse the measurement vial several times with the water to be
    tested, then fill to the 5 ml mark, Dry the vial on the outside.
    2. Add reagent drop by drop. Shake vial gently after every drop, until
    the color changes from blue via green to clear yellow.
    3. The number of drops used from the reagent corresponds to the
    existing carbonate hardness (in °dKH). E.g., 5 drops = 5°dKH.
    4. Cleaning: Clean the vial thoroughly with tap water before and after
    each test.
