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.

Review: Makes checking Nitrate level so much easier! No more trying to read the color chart and trying to figure out the difference between 40 and 80 or if the light you’re reading it in is good or is the light in the other room correct. It gives you an actual number!! You know exactly what your nitrate level is! It’s accurate too. I tested it against two different test kits and it matched what both of them said, so I trust it. Only negative is it takes about ten minutes total to run the test, start to finish, seven of the minutes is just you sitting there waiting on it to analyze the sample and give you the result. Also, it doesn’t beep when it’s finished and if you wait too long it will just shut off and you lose your reading. So be sure to set a timer so you’re there when the seven minutes is up. Some people complain about the powder packets being difficult to handle. I think they’re pretty easy. My technique is to just snip off the corner, then stick the tip of the scissors in to widen or open up the hole I just made. That creates a sort of a funnel for me to pour the contents into the bottle. I haven’t spilled any yet! Buy it now!!
