Nitrate Nitrogen Test Kit Procedure: Low Range(0-1.0ppm Nitrate Nitrogen) 1. Fill the water sampling bottle (0688) with the sample water. 2. Fill one test tube (0898) to the lower line (5mL) with sample water. 3. Dilute to second like with Mixed Acid Reagent (V-6278). Cap and mix. 4. Wait two minutes. 5. Use the 0.1g spoon (0699) to add one level measure (avoid any excess) of Nitrate Reducing Reagent (V-6279). 6. The mixing procedure is extremely important. Cap tube. Invert tube slowly and completely 30 times in 1 minute to insure complete mixing. 7. Wait 2 minutes. 8. Insert test tube into Axial Reader. Fill two test tubes to the 10mL line with sample water. Place in Axial Reader. Match sample color to a color standard. Record as ppm Nitrate-Nitrogen. High Range (0-10.0 ppm Nitrate Nitrogen)
