Hanna Checker - Nitrate HR (NO3) Colorimeter


The HI782 Nitrate Checker HC by Hanna Instruments is a simple and accurate handheld colorimeter that uses the zinc reduction method to determine nitrate concentration in marine applications.

The HI782`s high range of 0.0 - 75.0ppm makes it ideal for measuring the high nitrate levels found in saltwater aquariums. 





Why are Nitrate levels important?
Excess nitrates in a reef system can lead to an overgrowth of undesirable algae and dinoflagellates. Alternatively, not enough nitrates can lead to starvation for SPS and other corals.





  • Designed to accurately determine nitrate levels in aquariums and marine biology applications
  • Only requires 1 reagent for simplicity
  • No filter process
  • Measures with a range up to 75.0ppm
  • Easier to use and more accurate than chemical test kits
  • Dedicated to a single parameter
  • Simple one-button operation
  • Large LCD digital read out for added convenience
  • Auto shut-off to assure the battery wont be drained
  • Compact size for easy travel and storage


The HI782 Checker is a simple, accurate, and cost-effective way to measure nitrate in your saltwater aquarium.

Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of nitrates in a reef and fish only aquariums can promote the growth of undesirable organisms including algae and dinoflagellates which can quickly choke out filtration, lighting, and sessile organisms.
