Detect ammonia in process and cooling water to prevent copper corrosion and loss of biocide effectiveness. Fast, reliable on-site results with Indigo®test strips 0-100 ppm ammonia test strips.
Industrial cooling tower and process water systems can accumulate ammonia through biological activity, makeup water variability, or process contamination, creating conditions that increase copper corrosion and reduce biocide effectiveness. Indigo® 0–100 ppm Ammonia Test Strips provide a fast, practical way to monitor ammonia (NH3) and ammonium (NH4+) directly on site. Used by facility operators and water treatment professionals, these test strips support routine monitoring and troubleshooting with clear, color-matched results in seconds; no meters, reagents, or laboratory equipment required.
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").

Best Practices for Monitoring
Sample After Pre-Treatment: Test incoming make-up or recycled water before addition to the cooling loop.
Test After Biocide Dosing: Verify that chlorinated systems maintain residual effectiveness in the presence of ammonia.
Document Results: Record readings alongside conductivity and pH for trend analysis.
Investigate Spikes: Unexpected ammonia levels often indicate biofouling, dead zones, or wastewater carryover.
Cross-Check: Use nitrite or nitrate tests to track biological oxidation of ammonia in systems with biofilters or trickle towers.
