[Sample requirements]:

1. Take 5-10ml of the sample, and take the supernatant for testing after standing.

2. The test is carried out at room temperature around 25°C.

[Testing method]:

1. Immerse the reaction area of the test strip in the solution to be tested for 1-2 seconds, take out the test strip, and drain off the excess water on it.

2. After 30 seconds, compare the reaction area of the test strip with the color of the colorimetric card to determine the test value of the solution to be tested.

3. The colorimetric time should be controlled within 60s, and the reading will be affected if the time is too long or too short.

[Precautions]:

1. Do not touch the reaction end of the test strip when taking out the test strip, so as not to contaminate the test strip and affect the test results.

2. After taking out the required number of test strips, keep the remaining test strips sealed and protected from light.

3. The liquid to be tested should be kept as colorless or light-colored as possible. Before testing, the liquid with too dark color can be adsorbed with activated carbon for dehydration treatment. If the liquid to be tested is turbid, let it stand for a period of time, and then take the clear part for testing after precipitation.
