WaterWorks™ Nitrate / Nitrite nitrogen water test strips designed for in-home or on-the-go water testing for nitrates and nitrites. Ideal for well water testing, or routine home water tests. Safe, reliable test strips, no technical training is required. Color coded results.
Each strip offers two tests. Simply dip solution in water for 2 seconds, take the strip out, wait 1 minutes for the colors to develop. Then match Nitrate plus Nitrite (end pad) and Nitrite colors.
Nitrate and Nitrite Nitrogen (as N) test results are usually expressed as PPM (parts per million) or mg/L (milligram per Liter). To converrt of levels to NO2 and NO3, multiply Total Nitrate value by 4.4 to get NO3 mg/L, and multiply Nitrite value by 3.3 to get NO2 mg/L
