Description

The HI781 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 aquarium can promote the growth of undesirable organisms including algae and dinoflagellates while insufficient amounts can lead to starvation in which SPS and other corals will show signs including the loss of colour and paleness.

Utilising 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.

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 readout for added convenience
  • Compact size for easy travel and storage
