Product: Water hardness test set 2x 15 ml

Answer: That's difficult to answer. Depending on the hardness of the water, you need different numbers of drops. 1 drop roughly corresponds to about 0.05 ml. This means you can get about 300 drops per bottle. If the water hardness is 20 °dH, you need 20 drops per measurement. As a rule, you can therefore carry out between 15 and 30 measurements (depending on water hardness) per bottle.

Product: Water hardness test kit 1 reagent

Answer: The color always changes from the first drop. If the water hardness is greater than 0, the solution will initially turn red. You then count from the first drop until the solution turns green. If your water hardness is 0, the solution will immediately turn green.
