NITRITE WAP Nitrite DR900

1. Start program 373 N, Nitrite HR PP
2. Prepare 2,5 ml of water sample
3. Add treated water to sample up to 25 ml
4. Stir a minute to make sure that it’s really mixing
5. Fill a sample cell with 10 ml of sample
6. Add the contents of one NitriVer 2 Nitrite Reagent Powder Pillow
7. Close the sample cell, Shake to dissolve the reagent
8. Start the instrument timer. To prevent low results leave the sample on a flat surface
9. Fill a blank second sample cell with 10 ml of sample 10, Clean the blank,
10. Insert the blank into the cell holder.
11. Push Zero,
12. After the timer expires, gently invert the prepared sample two times,
13. Clean the prepared sample,
14. Insert the prepared sample into the cell holder,
15. Push read.
16. Result show in mg/L NO2- times by 10

Note: 10 values are ten times mixing between water sample and treated water.
