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 color
and paleness.
The HI781 Nitrate Checker HC is a handheld colorimeter that
uses the Beer-Lambert principle to determine the concentration
of nitrate colorimetrically. The HI781 is designed specifically
to measure low levels of nitrate in a saltwater aquarium.
