These test strips measure phosphate ions (PO4) in water including farm runoff, readings are at 0, 10, 25, 50 and 100 ppm levels; only $13.95.

These test strips can determine whether you have normal or high phosphate levels in your water runoff. Use along with our nitrate-nitrite test strips to monitor potential pollution levels.


Phosphate is essential to plant growth and excess runoff due to agricultural practices is a major contributor to the eutrophication of water both in lakes and freshwater. This test strip is very useful in Industrial and Agricultural wastewater management and environmental monitoring.

  • The number of strips (50) per vial is approximate.
  • Shelf life is 2 years but vial is lined with a desiccant and if properly sealed, strips can last 5 years.
