Designed for use with the HI774 Checker HC, these high-purity chemical reagents deliver fast, accurate phosphate readings from 0.00 to 0.90 ppm. Each packet is traceable with expiration and lot numbers, ensuring reliable and consistent water quality monitoring. ## Description The HI774-25 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Phosphate Ultra Low Range Checker HC. These reagents follow the Ascorbic Acid Method in which the reaction between phosphorus and reagents causes a blue tint in the sample. By simply adding the packet of HI774-25 reagent to the sample, the reaction will take place and the HI774 will determine the concentration from the color that is produced. The results will be displayed in ppb of phosphorus. These reagents are designed to be used with samples that have an expected range of 0.00 to 0.90 ppm phosphate.FEATURESPre-made reagents for ease of usePrepared with high purity chemicalsMarked with expiration date and lot number for traceability Review: Correct Replacements Review: Producto de calidad - Buenos producto ## 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 | B07SN7NSHP | | Brand | Hanna Instruments | | Brand Name | Hanna Instruments | | Container Type | Bag | | Country Of Origin | USA | | Customer Reviews | 4.8 out of 5 stars 370 Reviews | | Global Trade Identification Number | 00860012631049 | | Item Form | solid powder | | Item Weight | 0.03 Kilograms | | Manufacturer | Hanna Instruments | | Package Information | Bag | | Unit Count | 1 Count | ## Product Details - **Brand:** Hanna Instruments - **Item Form:** solid powder - **Item Weight:** 0.03 Kilograms - **Manufacturer:** Hanna Instruments - **Package Information:** Bag ## Images ![HI774-25 Phosphate Ultra Low Range Checker HC Reagents (25 Tests) by wwG Store - Image 1](https://m.media-amazon.com/images/I/41l36La1ipL.jpg) ![HI774-25 Phosphate Ultra Low Range Checker HC Reagents (25 Tests) by wwG Store - Image 2](https://m.media-amazon.com/images/I/61u4UPMTmrL.jpg) ![HI774-25 Phosphate Ultra Low Range Checker HC Reagents (25 Tests) by wwG Store - Image 3](https://m.media-amazon.com/images/I/51OxLxTtOeL.jpg) ![HI774-25 Phosphate Ultra Low Range Checker HC Reagents (25 Tests) by wwG Store - Image 4](https://m.media-amazon.com/images/I/51GeanJR42L.jpg) ## Questions & Answers **Q: it says expiration date 5/2021 , are they still usable?** A: Probably, they are dry reagents.
