Instructions for use
Determine the water sampleSee the table below;
Add 1 N0.1 tablet:Add an N0.1 tablet to the water sample and shake until dissolved;
Add tablet No. 2 until the solution turns pinkAdd a No.2 tablet to the water sample, shake until dissolved, observe the color, and then add another No.2 tablet to dissolve until the water sample turns pink and does not fade within one minute. remembernumber of pieces.
Calculate the concentration of nitrous acid：
Nitrous nitrogen mg/lNaNO2=No.2 tablet quantity x coefficient
| Range mg/l NaNO2 | Water sample volume | Usage coefficient |
| 140 - 1540 mg/L | 10 ml | 140 |
| 70-770 mg/l | 20 ml | 70 |
For example, taking 20 ml of water sample, adding one tablet of N0.1, and adding five tablets of No. 2, the water sample turns pink and does not change color for one minute. Therefore, the concentration of nitrite nitrogen in the water sample is 5 x 70=350 mg/lNaNO2
