• 1 bottle of 0.6 g of reagent A
• 1 bottle of 30 ml of reagent B
• 1 measuring spoon n°1
• 1 syringe of 5 ml
• 2 test tubes of 20 ml with stopper
• 1 optical comparator
• 1 chromatic scale
• Instructions (English)

• The method detects Cr+6. To detect Cr+3, it is necessary to determine total chromium by the photometric laboratory method (see Hydrocheck photometer manual). Cr+3 results from the difference between total chromium and Cr+6.
• 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).
