[Test Method]: 1. Dip the reaction area of the test strip into the solution to be tested for 1 to 2 seconds, remove the test strip, pull the edge of the test strip along the inside of the container, and drain any excess water. 2. After 30 seconds, compare the reaction area of the test strip with the color on the color chart to determine the test value of the solution. 3. The colorimetric time must be controlled within 60 seconds, and the reading will be affected if the time is too long or too short. [Precautions]: 1. When removing the test strip, do not touch the reaction end of the test strip to avoid contaminating the strip and affecting the test results. 2. After removing the required number of test strips, store the remaining test strips sealed and protected from light. 3. The liquid to be tested should be as colorless or clear as possible. Before testing liquids that are too dark, they can be dehydrated by adsorption on activated carbon. If the liquid to be tested is cloudy, let it stand for a while, then take the clear portion for testing after precipitation.
