The Hanna Instruments Marine Nitrate High Range Checker HC (HI782) is a pocket-sized digital colorimeter designed to quickly and accurately track elevated nutrient levels in marine systems. Engineered specifically for fish-only systems, mixed reefs, or aquariums with higher nutrient loads, this device utilizes an advanced optical system to deliver precise, lab-grade results. By replacing subjective, paper color charts with a bright digital LCD screen, it completely removes the human error of guessing shades of pink, letting you accurately monitor nitrates to prevent unwanted algae blooms.
📐 Technical Specs
Product Code: HI782
Measurement Range: 0.0 to 75.0 ppm (as NO₃⁻)
Resolution / Accuracy: 0.1 ppm / ±0.25 ppm ±2% of reading @ 25°C
Testing Chemistry: Zinc Reduction Method adaptation
Optical Engine: LED Light Source @ 525 nm with a Silicon Photocell
Compatibility: Exclusively developed for marine/saltwater testing
🌟 Key Benefits
Ultra-Simple 1-Reagent Process: Unlike the tedious filtering steps required by low-range checkers, the high-range model uses a simplified, filter-free method that requires only a single powder reagent packet per test.
No More Color Guesswork: Delivers a definitive, digital parts-per-million reading on a high-contrast display screen, eliminating the frustration of visual titration kits.
Engineered for High-Nutrient Tanks: The wide 75.0 ppm ceiling makes it the ideal diagnostic tool for heavily-stocked fish-only setups, soft coral tanks, and large systems where nutrients run naturally higher.
Built-In Reaction Timer: Features an integrated 7-minute countdown clock that ensures your sample reacts for the exact required duration before taking an optical snapshot, guaranteeing maximum accuracy.
