Hanna Nitrate Checker HC (HI782)

Easily monitor nutrient build-up in your reef tank with the Hanna HI782 High Range Nitrate Checker HC. Specially developed for saltwater systems, this digital tester delivers fast, precise nitrate readings up to 75 ppm—ideal for fish-only systems, mixed reefs, and tanks with elevated nutrient levels.

🔹 Why choose the high range model?
While ULNS systems demand ultra-low testing, many reef setups operate safely at higher nitrate levels. This checker helps manage nutrient dosing and feeding regimens while avoiding algae outbreaks or coral stress.

🔹 Key Features:

• Measures nitrate in the 0.0–75.0 ppm range

• Specifically designed for marine water

• Digital display eliminates interpretation errors

• High accuracy with ±2.0 ppm resolution

• Ideal for tanks with moderate to high bioload

• Includes reagents for 25 tests, cuvettes, syringes, and battery

🔹 Perfect for:

• Mixed reefs and fish-dominated tanks

• Systems where nitrate is intentionally elevated (e.g. soft coral or zoa tanks)

• Aquarists balancing nitrate and phosphate ratios (Redfield ratio)

🔹 What’s included:

• HI782 Nitrate HR Checker

• Sample cuvettes with caps

• Mixing vials, syringes, and pipettes

• Reagents for 25 tests

• Battery & instruction manual

Whether you're correcting nutrient imbalances or just tracking your system’s health, the Hanna HI782 offers fast and reliable results—perfect for modern reefkeepers who want clarity and control.
