Test Method:
1. Immerse the reaction area of the test strip into the test solution for 1-2 seconds, remove the test strip, and shake off any excess water.
2. One minute later, compare the reaction area of the test strip with the color of the color card to determine the test value of the test solution.
3. Colorimetric time should be controlled at about 60 seconds. If the time is too long or too short, it will affect the reading.

Attention:
1. Please do not touch the test area of the reagent strip.
2. Remove the test strip after use and keep the remaining test strips sealed and away from light.
