Use Indigo® ammonia test strips to monitor nitrification efficiency and discharge compliance in wastewater and sewage treatment systems.

Indigo® Instruments 0-100 ppm ammonia test strips provide a fast, practical way to monitor ammonia (NH3) and ammonium (NH4+) levels in wastewater and treated effluent. Commonly used by treatment plant operators, engineers, and environmental technicians, these strips support routine checks of nitrification performance, process stability, and upset conditions. Results are available in seconds via a clear color comparison, allowing immediate field or bench-top screening without reagents, meters, or sample preparation.

We've been selling ammonia test strips since 2014. Buy fully documented Indigo® ammonia test strips, 25 strips/vial, with a guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd").

Learning Outcomes by Discipline

Discipline Learning Outcomes / Key Features
Environmental Engineering Evaluate nitrification efficiency and process control through ammonia concentration monitoring.
Chemistry / Environmental Chemistry Understand redox and biochemical pathways converting ammonia to nitrite and nitrate in aerated systems.
Biotechnology / Microbiology Relate bacterial metabolism (Nitrosomonas, Nitrobacter) to ammonia oxidation and treatment efficiency.
Public Health / Regulatory Studies Explain how ammonia testing supports NPDES compliance and protects aquatic ecosystems.

Best Practices

  • Test effluent daily or per shift to confirm biological system stability.
  • Calibrate treatment aeration to maintain DO > 2 mg/L for effective nitrification.
  • Use test strips for rapid screening, then confirm high results via laboratory analysis.
  • Implement trend tracking to anticipate upsets before discharge violations occur.
  • Maintain biofilm carriers or activated sludge to support robust nitrifying populations.
