HI781 Marine Nitrate Checker HC Handheld Colorimeter – Hanna Instruments

The HI781 Nitrate Checker HC by Hanna Instruments is a simple and accurate handheld colorimeter that uses the Beer-Lambert principle to determine nitrate concentration. The HI781`s low range of 0.00 – 5.00 makes it ideal for measuring the low 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.

Features:

  • Low range is ideal for saltwater aquariums 
  • Easier to use and more accurate than chemical test kits
  • Dedicated to a single parameter
  • Simple one-button operation
  • Digital read out for added convenience
  • Compact size for easy travel and storage
