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:

• 'Zero' the Checker HC as required in the specific procedure
• Add reagent to your water sample
• Place the vial into your Checker HC
