HI782 High Range Nitrate Checker vs HI781 Low Range Nitrate Checker
The HI782 was designed to quickly and easily measure nitrate levels for aquarists 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
