• 2 bottles of 20ml of reagent A
• 1 bottle of 20ml of reagent B
• 1 syringe of 5ml
• 2 test tubes of 20ml with stopper
• 1 optical comparator
• 1 chromatic scale
• Instructions (English)

• The analysis according to Nessler is a classic method, tested for a century. The indophenol method offers higher sensitivity.
• The optical comparator contained in the package allows the comparison of the color between two test tubes containing the same amount of water, so as to improve the accuracy of the result.
• HYDROCHECK kits (which can be purchased directly) allow to perform a variety of precise analyses at a very low cost per analysis. If accuracy is not mainly important and there are few analyses to be performed, it may be favorable to use DROPS kits, whose cost per package is considerably lower (to be purchased through resellers).
