Nitrate is reduced to nitrite in the presence of cadmium. The nitrite thus produced reacts with the reagent to yield an orange compound. The amount of color developed is proportional to the concentration of nitrate present in the aqueous sample.
Colorimetric
Chemical test kit for the determination of nitrate in water in the range 0-50mg / l (ppm). Package size: 100 Tests
The HANNA test kit for ozone determines the ozone concentration in water via checker disc. The reaction between ozone and the reagent causes a pink tint in the sample which is proportional to the ozone concentration.
