Hanna HI774-25 Marine phosphate

Hanna HI774-25 Reagents for Marine Phosphate Ultra Low Range Checker HC

The Hanna HI774-25 reagent packets are specially formulated for use with the HI774 Marine Phosphate Ultra Low Range Checker® HC, enabling users to achieve accurate, consistent, and easy phosphate measurements in saltwater aquariums and marine research environments. These pre-measured reagents utilize the Ascorbic Acid Method, based on Standard Methods for Water and Wastewater testing.

Ideal for reef aquarium keepers, aquaculture professionals, and environmental scientists, HI774-25 reagents ensure ultra-sensitive detection of phosphate levels that can impact coral growth and water quality.

Key Features:

• Ultra Low Range Detection: Measures phosphate levels from 0.00 to 0.90 ppm, ideal for marine environments where precision is essential.

• High Accuracy: Provides reliable results with ±0.02 ppm ±5% of reading at 25°C.

• Colorimetric Method: Phosphate reacts with the reagent, producing a color change that is read by the HI774 Checker HC.

• Pre-Measured Convenience: Each packet contains the exact amount of reagent needed for one test—no measuring, mixing, or guesswork.

• Fast and Simple: Easy-to-use packets deliver results in minutes, making routine testing efficient and repeatable.
