Nitrate Test Strip
The Nitrate test strip is used to detect Nitrate in solution at 10, 25, 50, 100, 250, & 500ppm. Nitrate test strips are often used to test fertilizer run-off in agricultural areas. This strip is very sensitive to light and moisture, so be sure to keep the vial tightly sealed. For a dual Nitrate-Nitrite test, check out or combo test strip with both tests in one.
- Remove one test strip from the container. Do not touch the test pad to your finger.
- Dip the test pad into the solution being tested for 2-3 seconds.
- Remove the strip and shake off excess liquid.
- Compare to the color chart after 1 minute.
