Procedure for NO₃-N measurement

Before you start take into account the following:

  • Rinse tubes with sample before the analysis.
  • Rinse tubes with deionized water after the analysis.
  • Dilute the sample if the nitrate-nitrogen concentration exceeds 40 mg/L.

Testing procedure

Fill two tubes to the first line with sample. Install the first tube into the left opening of the color comparator box. Add the content of NitraVer 5 Nitrate Reagent Powder Pillow to the second tube, install the cap and shake the content of the second tube for 1 minute. After 1 minute, amber color appears. Set the second tube into the color comparator box. While holding the color comparator box in front of the light, rotate the disk to find a color match. Evaluate the testing results in mg/L in the scale window.

To record the test result as mg/L NO3, multiply the test result by 4.4.
