Hanna HI782 Marine Nitrate High Range Checker
The Hanna HI782 Marine Nitrate High Range Checker is an essential colorimetric tool designed for accurate monitoring of nitrate levels in saltwater aquariums. Maintaining appropriate nitrate concentrations is crucial for supporting marine life health, particularly in fish-dominated systems or mixed reef tanks where nutrient loads may be higher.
Developed specifically for use with seawater samples, the HI782 offers quick and reliable results using a zinc reduction method, delivering accurate measurements without the subjectivity of color-matching charts typically associated with chemical test kits.
Key Features
High Range Capability: Measures nitrate levels from 0.0 to 75.0 ppm, ideal for marine tanks with higher biological loads.
Zinc Reduction Method: A trusted method that produces a pink tint in the presence of nitrate, allowing precise digital quantification.
Exceptional Accuracy: Provides results with an accuracy of ±2.0 ppm ±5% of reading, ensuring confident water quality adjustments.
User-Friendly Design: Compact and ergonomic form factor with easy one-button operation and a large digital display.
Automatic Shut-Off: Conserves battery life by powering down after 10 minutes of inactivity.
Applications
Saltwater and reef aquariums
Marine aquaculture facilities
Environmental marine studies
Water quality management in ocean-based research
