Using the Zinc reduction method, these reagents deliver fast, reliable results within a 0-75 ppm nitrate range, with each packet clearly marked for expiration and lot traceability—ideal for professionals committed to maintaining optimal marine water quality. ## Description The HI782-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Marine Nitrate High Range Checker HC. These reagents follow the Zinc reduction method in which the reaction between nitrate and the reagent causes a pink tint in the sample. By simply adding the packet of HI782-25 reagent to the sample, the reaction will take place and the HI782 will determine the concentration from the color that is produced. The results will be displayed in ppm of nitrate (as NO3–). These reagents are designed to be used with saltwater samples that have an expected range of 0.0 to 75.0 ppm.FEATURESPre-made reagents for ease of usePrepared with high purity chemicalsMarked with expiration date and lot number for traceability ## Features - Pre-made reagents for ease of use - Prepared with high purity chemicals - Marked with expiration date and lot number for traceability ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B098V2XKP6 | | Best Sellers Rank | #11,407 in Pet Supplies ( See Top 100 in Pet Supplies ) #14 in Aquarium Test Kits | | Brand | Hanna Instruments | | Brand Name | Hanna Instruments | | Customer Reviews | 4.8 out of 5 stars 571 Reviews | | Global Trade Identification Number | 00198715292268 | | Item Form | Powder | | Manufacturer | Hanna Instruments | | Manufacturer Part Number | HI782-25 | | Model Number | HI782-25 | | Target Species | brackish water fish | | Unit Count | 25.00 Count | ## Product Details - **Brand:** Hanna Instruments - **Global Trade Identification Number:** 00198715292268 - **Item Form:** Powder - **Manufacturer:** Hanna Instruments ## Images ![HI782-25 Marine Nitrate High Range Checker Reagents (25 Tests) - Image 1](https://m.media-amazon.com/images/I/512l5veYmYL.jpg) ## Questions & Answers **Q: I ordered this and the regent powder is clumpy.
