Nitrate and Nitrite Test Strips

Product #: 2745425


Excessive amounts of nitrate or nitrite in water can cause infant death, adult illness, and can produce spontaneous abortion in cows. Some wells contain high levels of nitrate. When water contains high nitrate levels, nitrites are often present in low concentration. Contains 25 tests.

  • Easy to use, disposable, and inexpensive
  • A great way to obtain quick, quantitative answers in the field or in the lab
