Pre-measured and carefully formulated, these reagents simplify testing by letting you add a single solution to your sample and interpret the result by color development. The colorimetric reaction progresses from yellow through green to blue, giving a visual cue that aligns with the reported dKH value on the checker.\u003c\/p\u003e\n\u003ch3\u003eKey product benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePre-made reagents for ease of use\u003c\/li\u003e\n  \u003cli\u003ePrepared with high-purity chemicals\u003c\/li\u003e\n  \u003cli\u003eExpiration date and lot number marked for traceability\u003c\/li\u003e\n  \u003cli\u003eDesigned for 0.0 to 20.0 dKH samples\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat you get and how it works\u003c\/h3\u003e\n\u003cp\u003eEach HI772-26 kit provides a small, clean set of reagents that are ready to use, minimizing handling steps and potential measurement errors. The high-purity formulation supports reliable color development, which the Marine Alkalinity Checker HC translates into dKH readings. The system is built around a colorimetric method, where sample reaction yields a distinct color range that correlates with alkalinity levels.\u003c\/p\u003e\n\u003ch3\u003eUsage tips for real-world testing\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCollect a representative water sample under stable conditions.\u003c\/li\u003e\n  \u003cli\u003eAdd the pre-measured HI772-26 reagent to the sample per the instrument guide.\u003c\/li\u003e\n  \u003cli\u003eObserve the color change and compare to the device’s scale for an estimated dKH value.\u003c\/li\u003e\n  \u003cli\u003eRepeat as needed to confirm consistency across measurements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eQuality and inventory control\u003c\/h3\u003e\n\u003cp\u003eTraceability features help you manage quality and replenishment.
