Product: Water hardness test set 2x 15 ml
Answer: The set has a shelf life of up to 2 years. It should then be replaced.
Product: Water hardness test set 2x 15 ml
Answer: You're not doing anything wrong. This only means that the water has a hardness of 0°dH (1 drop = 1°dH)
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: Yes, with the Filtrasoft water hardness test set you can basically also determine the hardness of filtered water, such as that from a table filter. The test kit is designed to measure the overall hardness of water, whether it comes straight from the tap or has gone through a filter.
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.
