Acidic pH Levels Test Indicators, 4-7

You can use acidic pH level indicator test papers in the 4.0-7.0 range for measuring weakly acidic liquids such as urine . They are also recommended for accurate testing of saliva which is typically in the range of pH 6.3-6.5. If you are interested in your drinking water, from the tap or bottle, you should expect to see a reading between 5.5 & 6.0. Under "just distilled" conditions, water should be neutral, pH 7, but since CO₂ readily dissolves in water, it forms a mild solution of carbonic acid, which makes it closer to pH 5.6. These acid test strips can also be used for detecting yeast infections which occur in the 3.8-4.2 range.

Note: The number of strips per pack or vial is approximate.

Narrow pH range 4.0-7.0; resolution is 0.5 pH unit
Test drinking water ; typically pH 5.6.
Test saliva; typically pH 6.3-6.5.
Urine can be pH 5-8
