3.Shake off excess liquid.
4.Wait 60 sec.
5.Compare with the color scale. If nitrite ions are present,the test field turns orange to red.
Measuring range:0.1-3 g/L NO2-,100-3000 PPM NO2–
Color Gradation: 0=0 PPM NO2–
0.1=100 PPM NO2–
0.3=300 PPM NO2–
0.6=600 PPM NO2–
1=1000 PPM NO2–
2=2000 PPM NO2–
3=3000 PPM NO2–
