【Universal pH Test Strips】
Our universal pH test strips not only measure human pH levels via saliva or urine but are also widely used in scientific education, laboratory testing, household drinking water, swimming pools, hot springs, aquariums, hydroponic gardening, and more.

【Usage Steps】
Step 1
Immerse the colored end of the tester strips into the liquid for 2 seconds, then remove and wait 15-30 seconds before comparing colors with the color chart.
Step 2
Compare the first color band on the strip with the first row of the chart. The closest match indicates the approximate pH value. If no match is found in the first row, compare the second color band with the second row, and so on. The corresponding pH value is determined by the closest color match.

【Precautions】
1. When removing the pH test strips, avoid touching the reaction zone (color block area) at the front end with your fingers to prevent contamination!
2. The liquid being tested should be colorless or nearly colorless. Colored liquids require decolorization treatment before testing to prevent affecting the results!
