Manufactured with care to high-purity standards, these packets arrive pre-measured for quick, repeatable tests without sacrificing accuracy.\u003c\/p\u003e\n\u003cp\u003eIn practice, the chemistry behind the HI782-25 uses a zinc reduction reaction that yields a pink tint in your sample. The intensity of the color corresponds to nitrate levels, and your HI782 reader translates that into a readable ppm NO3- value. This setup is intended for saltwater contexts with expected nitrate ranges from 0.0 to 75.0 ppm.\u003c\/p\u003e\n\n\u003ch2\u003eWhat makes HI782-25 unique\u003c\/h2\u003e\n\u003cp\u003eThese reagents are built for ease of use and reliable results.
