Get fast, reliable color results for nitrate & nitrite in water, food, and biological systems in teaching laboratories, industry & environmental monitoring with Indigo^® Nitrite-Nitrate test strips.

Indigo® Nitrite-Nitrate Test Strips provide a fast, semi-quantitative method for detecting reactive nitrogen species across water, food, and biological systems. Common applications include drinking water screening, aquaculture and aquarium monitoring, agricultural runoff, hydroponic nutrient solutions, soil and substrate extracts, and food processing checks. Each strip produces a clear colorimetric result in under one minute using an easy-to-read chart covering 0-50 mg/L (ppm) nitrite and 0-500 mg/L (ppm) nitrate; no reagents, meters, or glassware required.

We've been selling nitrate-nitrite test strips since 2009. Buy fully documented Indigo® nitrate-nitrite test strips, 50 strips/vial. Guaranteed 3 year shelf life (dated back from expiration date "yyyy.mm.dd").

Tips for Best Results

Use clean, clear samples — cloudy or colored water can distort readings.
Dip for 1 second and read within 60 seconds under consistent lighting.
Avoid touching the test pads; handle from the top edge only.
Store strips tightly capped in a cool, dry place.
Record color results immediately for consistent comparisons.
