Operation method:

colorimetry

1.Take the water sample to be tested and rinse the test tube2Next, add the water sample to the test tube until it reaches the mark on the tube;

2.Add the reagents to the test tube in sequence according to the instructions on the back of the color chart;

3.Shake the test tube to dissolve or mix evenly;

4.After the reaction is complete, place the test tube on the edge of the color chart (or white paper) and visually compare the color from top to bottom (single eye color comparison is better). The color tone inside the tube that is the same or similar to the standard color on the color chart is the test result of the water sample.

be careful:Some indicators may have special operational requirements, please read the instructions on the back of the color chart carefully before use.

Titration method

1.Take the water sample to be tested and rinse the test tube2Next, add the water sample to the test tube until it reaches the mark on the tube;

2.Add the reagents into the test tube in sequence according to the operating instructions

3.Shake the test tube to dissolve or mix evenly.

4.Add reagents dropwise into the test tube

5.Shake the test tube while dripping, and stop titration when the color of the water sample in the tube changes. Record the number of drops and perform a simple calculation to obtain the test result of the water sample

be careful:Some indicators may have special operational requirements, please read the instructions on the back of the color chart carefully before use.
