Note:

1. When removing the test strip, do not touch the reactive end of the test strip to avoid contaminating the test strip and affecting the test results.

After removing the required number of test papers, keep the remaining test papers sealed and protected from light. 3. Try to keep the liquid to be tested colorless or only slightly colored. Before testing a liquid that is too dark, it can be dehydrated by adsorption onto activated carbon. If the liquid to be tested is relatively cloudy, let it stand for a while and take the clear portion for testing after it has stabilized.
