The HI784-25 provides 25 tests worth of replacement reagents for the Hanna Instruments Marine Ammonia Checker HC (HI784), keeping the checker operational without requiring any additional equipment. The reagents use the colorimetric salicylate method: when ammonia or ammonium is present in a saltwater sample, a reaction with the reagent produces a blue-green tint, and the HI784 reads the resulting color to determine concentration in ppm.
Each pack contains three reagents — HI784A-0, HI784B-0, and HI784C-0 — that work together to complete the colorimetric reaction. The reagents are pre-measured, eliminating the need for manual dilution or preparation and reducing the chance of user error between tests. They are formulated with high-purity chemicals and produced in a controlled manufacturing environment.
Every packet is printed with its lot number and expiration date, so you can verify reagent integrity and trace results back to a specific production batch. The HI784-25 is calibrated for saltwater use and covers a measurement range of 0.00 to 2.50 ppm ammonia — suitable for routine monitoring in reef and marine fish systems. These reagents are not compatible with other Hanna checker models; confirm you are running the HI784 before ordering.
