The HI782 was designed to quickly and easily measure nitrate levels for aquarist with higher-than-average nutrient levels. This includes saltwater aquariums that are fish-only or have corals that can tolerate elevated levels of nitrate at 30 ppm or more.
Very low levels of nitrate are critical for many saltwater reef aquariums, as nitrate can cause damage and possible death to certain delicate corals and invertebrates. For this reason, the HI781 offers unmatched precision in the measurement of very low levels of nitrate (0.00 to 5.00 ppm). For freshwater samples, Hanna Instruments recommends using the HI97728 Nitrate Portable Photometer.
