The HI782 Checker® HC for Nitrate in Marine Water is a handheld colorimeter that determines nitrate concentration colorimetrically using the Beer-Lambert principle. HI782 is specifically designed to measure high nitrate concentrations in a marine aquarium. The range of 0.0 to 75.00 ppm is suitable for reef aquariums stocked with fish or fish and corals. Nitrate is a byproduct of the nitrogen cycle. Too high a nitrate level in a reef aquarium can promote the growth of undesirable organisms, including algae and dinoflagellates, while insufficient levels can lead to coral bleaching.
