Monitor nitrate and nitrite levels in farm irrigation, hydroponic nutrient solutions, and soil runoff with quick, reliable Indigo® Nitrite-Nitrate test strips.

Nitrate and nitrite levels are key indicators of nitrogen availability and nutrient balance in agricultural and hydroponic systems. Indigo® Nitrate-Nitrite Test Strips provide a fast, practical way to monitor irrigation water, hydroponic nutrient solutions, and runoff before excess nitrogen affects crop health or system performance. Simple dip-and-read testing allows growers to make timely fertilizer and nutrient adjustments without instruments, reagents, or laboratory delays.

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").
