Hanna Marine Nitrate HIgh Range Checker HI782
Hanna Marine Nitrate HIgh Range Checker HI782
Nitrate is the final step in the Nitrogen cycle. Excessive amounts of nitrates in saltwater aquariums facilitate the growth of undesirable organisms such as algae and dinoflagellates. The HI782 is a simple, accurate, and cost-effective way to measure nitrate from 0.0 to 75.0 ppm (as NO3–) in your saltwater aquarium.
The HI782 Nitrate Checker HC uses the Zinc Reduction method to measure the concentration of nitrate colorimetrically. The HI782 provides quick, accurate results in four easy steps.

HI782 High Range Nitrate Checker vs HI781 Low Range Nitrate Checker
_x000D_The HI782 was designed to quickly and easily measure nitrate levels for aquarists with higher-than-average nutrient levels. This includes saltwater aquariums that are fish-only or have corals that can tolerate elevated levels of nitrate at 30 ppm or more.
Very low levels of nitrate are critical for many saltwater reef aquariums, as nitrate can cause damage and possible death to certain delicate corals and invertebrates. For this reason, the HI781 offers unmatched precision in the measurement of very low levels of nitrate (0.00 to 5.00 ppm). For freshwater samples, Hanna Instruments recommends using the HI97728 Nitrate Portable Photometer.
