How to Use the HI-97728 for Nitrate Testing

  1. Prepare Samples: Clean cuvettes and fill with your water sample (10 mL required).
  2. Zero the Photometer: Insert the blank cuvette and press the button.
  3. Add Reagents: Use powder or liquid reagents, based on your preference, to trigger the nitrate reaction.
  4. Measure Results: Return the cuvette to the photometer and read nitrate levels directly on the backlit LCD screen.

Why Nitrate Testing Matters

Nitrate is a key indicator of water quality, often stemming from fertilizers, sewage, and organic matter decomposition. While beneficial in small amounts, excessive nitrate contributes to eutrophication, reducing dissolved oxygen and disrupting aquatic ecosystems. Regular monitoring with the HI-97728 ensures optimal nitrate management in water sources.

Ideal Applications

  • Environmental Monitoring: Detect and control nitrate levels in rivers, lakes, and streams.
  • Agriculture: Optimize fertilizer use while mitigating runoff.
  • Wastewater Treatment: Analyze and manage nitrate in discharge water.
  • Drinking Water Safety: Ensure compliance with water quality standards.

Upgrade to Reliable Nitrate Testing

Combining advanced optics with intuitive functionality, the HI-97728 Nitrate Portable Photometer sets a new standard for water quality analysis. Its compact build, precision calibration, and versatile applications make it the trusted choice for professionals worldwide.
