- The optical comparator contained in the package allows for color comparison between two test tubes containing the same amount of water, benefiting accuracy.
- HYDROCHECK kits (which can be purchased directly) allow for many precise analyses at a very low cost per analysis. If accuracy is not particularly important and there are few analyses to be performed, it may be worthwhile to use DROPS kits, whose cost per package is considerably lower (to be purchased through dealers).
