Indigo® Nitrite-Nitrate test strips measure nitrite in 0 to 25ppm & nitrate in 0-500ppm levels simultaneously in ground, well or drinking water; only $17.95/50 strips.

Nitrate is reduced to nitrite quickly in well-aerated soils and bioreactors by aerobic bacteria. These test strips can help determine rates of nitrification, nitrite removal & biological oxygen demand. They can also be used to determine levels in wine, seafood and charcuterie meats.

See below for Certificate of Analysis, SDS & Stability documents.


Nitrate and nitrite test strips can be used to test water quality in farm runoff, groundwater or in bioreactors for conversion of ammonia to nitrate. These are also a simpler alternative to the "brown ring test".

  • Nitrate is measured in increments of 10, 25, 50, 100, 250, & 500ppm
  • Nitrite is measured in increments of 1, 5, 10, & 25ppm
  • The number of strips (50) per vial is approximate.
  • These strips are extremely sensitive to airborne humidity. Reseal the desiccant lined bottle immediately after removing a strip to ensure 3 year shelf life.
