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.
For use with saltwater samples. More accurate than chemical test kits. Dedicated to a single parameter. Small size, big convenience. No errors with a digital readout. Ideal for aquariums and marine biology applications.
HI782 High Range Nitrate Checker vs HI781 Low Range Nitrate Checker
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.
