The HI781 Checker®HC (Handheld Colorimeter) is a simple, accurate and cost-effective way to measure nitrate in saltwater.

Nitrate is a bi-product of ammonia.

It comes from fish waste, plant decay, and leftover food.

Over time, nitrate can build up in your aquarium. While low levels are not harmful, too much nitrate can be detrimental to the health of your fish and plants.

Both odorless and colorless, nitrate can only be detected by testing.

Designed as a more accurate alternative to chemical test kits, the HI781 marine nitrate meter provides quick,

accurate results in a few easy steps.


  • For use with saltwater samples
  • Easier to use and more accurate than chemical test kits
