WaterWorks™ Nitrate/Nitrite Eco Packs (NCW-481109)

Part No: NCW-481109

This simple dual colour test strip, from our WaterWorks™ brand, allows for quick and accurate testing of Nitrates and Nitrites in water, as Nitrogen. It has been designed with two separate test pads on the same strip.


It is a simple dip and read test strip with a precise colour chart on the back of the bottle and the results are shown within 60 seconds. These strips are ideal for field, on-site and lab use. No other reagents or accessories are needed for this test. We use trace amounts of chemicals on our strips which makes them extremely safe and non-hazardous. They are considered as Articles under OSHA and do not require SDS sheets. This is our new recyclable packaging.

Why test for Nitrate and Nitrite? This test detects Nitrate and Nitrite measured as Nitrogen (NO3-N & NO2-N). Nitrate and Nitrite find their way into drinking water from farm fertilizer, industrial and biological waste, and naturally forming mineral deposits. Their presence can often be a sign of other pollutants in the water. Nitrate (NO3-N) levels above 10ppm are linked to “blue baby syndrome” in infants. The EPA sets the limit for Nitrate (NO3-N) at 10ppm; the limit for Nitrite (NO2-N) is 1ppm. Nitrite (NO2-N) levels above the EPA limit can be an indicator that bacteria are present. The WHO guideline value for Nitrate (NO3) is 50 mg/L and for Nitrite (NO2) 3mg/L.

  • Nitrate (as NO3-N): 0, 0.5, 2.0, 5, 10, 20, 50 ppm (mg/L)
  • Nitrite (as NO2-N): 0, 0.15, 0.3, 1.0, 1.5, 3.0, 10.0 ppm (mg/L)
  • *Note: For conversion of Total Nitrate (NO3-N) to NO3 multiply value by 4.4. For conversion of Total Nitrite (NO2-N) to NO2 multiply value by 3.3.
  • Nitrate (as NO3): 0, 2, 10, 20, 50, 100, 200 ppm (mg/L)
  • Nitrite (as NO2): 0, 0.5, 1, 3, 5, 10, 30 ppm (mg/L)
