Hanna HI782-25 Marine Nitrate High Range tests

Hanna HI782-25 Marine Nitrate High Range tests

The Hanna HI782-25 Marine Nitrate High Range tests designed for use with the HI782 Marine Nitrate High Range Checker HC, enabling fast, accurate, and easy nitrate testing in saltwater environments. These high-quality reagents use the zinc reduction method, producing a pink color in the sample that the checker digitally analyzes for nitrate content.

Each reagent packet is pre-measured, ensuring consistent results with minimal handling—perfect for reef aquarists, marine biologists, and saltwater system professionals who rely on accurate water chemistry for coral and marine life health.

Key Features:

• Specifically for Saltwater Use: Designed to work with seawater samples, making it ideal for reef and marine aquariums.

• Pre-Measured for Convenience: Each packet contains the exact amount of reagent needed for one test—no measuring or guesswork required.

• Zinc Reduction Method: Converts nitrate to a detectable compound that forms a pink tint for digital analysis.

• High Accuracy: Achieves ±2.0 ppm ±5% of reading for reliable and repeatable results.

• Compatible with HI782 Checker: Optimized for use with the HI782 Marine Nitrate High Range colorimeter.

How It Works:

1. Add your seawater sample to the cuvette.

2. Add the contents of one HI782-25 reagent packet.

3. Mix the solution as instructed.

4. Insert the cuvette into the HI782 Checker HC.

5. The device will measure the color intensity and display nitrate concentration in ppm.
