---------------------------------------------------------------------- pH range: 4.5-9. ANTHROPOLOGY MEASUREMENT: High accuracy, suitable for anthropometry and weak acid/alkali measurement. The sample has a decimal point (pull down to see the photo) for direct comparison. Note: For saliva testing, the best time to test your saliva pH is in the morning before brushing your teeth with the test strip. During the day, it's best to test two hours after eating, after swallowing three times. Dip the strip into your saliva for 0.5 seconds, then wait 5-10 seconds before comparing the results with the color card. How to use the test strips: Immerse all two color blocks directly into the liquid, remove them after 1-2 seconds, shake off excess water, and immediately compare the samples to find the closest value set (invalid after the liquid has evaporated). pH: A pH below 7 is acidic, equal to 7 is neutral, and above 7 is alkaline.
