potable, wastewater, purified and of swimming pool

• 1 bottle of 35 ml of reagent A
• 1 bottle of 18 ml of reagent B
• 1 syringe of 5 ml
• 2 test tubes of 20 ml with stopper
• 1 optical comparator
• 2 chromatic scales
• Instructions (English)

• The method is recommended for measuring free chlorine in water containing interfering substances, for example swimming pool water.
• 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).
