Description The HI782 Marine Hanna nitrate checker high range colorimeter is specifically designed to quickly and accurately determine high levels of nitrate for saltwater aquariums and marine applications. With a digital read out, there is no more struggling to determine colors visually. Measurements with a range up to 75.0ppm Less complex laboratory grade accuracy – Requires only 1 reagent Simple, intuitive operation Compact and precise whether at home, at work, or on-the-go. HI782 High Range Nitrate Checker vs HI781 Low Range Nitrate Checker The HI782 Hanna nitrate checker 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.
