• 2 bottles of 25 ml of reagent pH 5 - 11
• 1 bottle of 25 ml of reagent pH 0 - 5

- The optical comparator contained in the package enables a color comparison between two test tubes containing the same amount of water, which increases accuracy.
- The HYDROCHECK kits (which can be purchased directly) allow many precise analyses to be carried out at a very low cost per analysis. If precision is not particularly important and the analyses to be carried out are few in number, it may be worthwhile using DROPS kits, which cost considerably less per package (to be purchased through dealers).
