## Description

Product description The HI782-25 are the replacement reagents for the HI782 Marine Nitrate High Range Checker HC. These high-quality reagents are manufactured in our state-of-the-art facility and are clearly marked with the lot number and expiration date on each packet for traceability. rate High Range Checker Reagents (25 Tests) OUT OF STOCK 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. Directions Simply add the HI782-25 reagent package to the sample, the reaction will occur, and the HI782 will determine the concentration of the color that is produced.

Review: Consistent and Well Packaged - These reagents do what they’re meant to do. They’re simple to use with the HI 782 checker and the readings have been consistent and accurate for me. The packets are well sealed and easy to open. You only get 25 tests, so last well for what you pay, so they’re not the cheapest per test, but Hannah reliability isn’t questionable.
