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:
