The reagents are pre-measured to simplify your testing workflow, reducing prep steps while supporting accurate readings across multiple samples.\u003c\/p\u003e\n\u003cp\u003eThe colorimetric method used here yields a distinct color progression, moving from yellow to green to blue as alkalinity levels rise. When you compare the sample color to the checker’s scale, the device reports a dKH value, typically within the 0.0 to 20.0 dKH range. This setup aims to provide clear, interpretable results without guesswork, ideal for hobbyists and professionals who monitor reef tanks, aquariums, or small marine systems.\u003c\/p\u003e\n\n\u003ch3\u003eWhat you get and how it helps your workflow\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePre-measured reagents designed for quick testing\u003c\/li\u003e\n  \u003cli\u003eHigh-purity chemicals to support reliable readings\u003c\/li\u003e\n  \u003cli\u003eLabels include expiration date and lot number for traceability\u003c\/li\u003e\n  \u003cli\u003eIncludes 25 tests per kit to support routine monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eTo get the most out of the HI772-26 set, follow the included instructions for sample collection and reagent addition.
