Checker Nitrates for Seawater, Wide Range HI782 Hanna Instruments

The HI782 is a digital mini-photometer developed by Hanna Instruments for measuring nitrates in seawater. It enables reliable and quick monitoring of this essential parameter for maintaining the biological balance of a marine aquarium.

Why Measure Nitrates in a Marine Aquarium

Nitrates mainly come from fish waste and leftover food. A high concentration promotes algae growth and can cause significant stress for fish and invertebrates.

The recommended nitrate level is below 10 mg/L. Beyond 50 mg/L, a partial water change is generally necessary to limit imbalances.

Measurement Principle

The Checker HI782 uses a colorimetric method. After adding the reagent, the sample develops a coloration proportional to the nitrate concentration. The color intensity is analyzed by the photometer to provide an accurate numerical value.
