Description
Universal pH Test Strips are easy-to-use indicator strips designed to quickly measure the acidity or alkalinity of a solution. Each strip is coated with a special pH-sensitive dye that changes color when dipped into a liquid, giving an accurate reading across a broad range, typically pH 1–14.
They are widely used in:
• Laboratories – for quick testing in experiments and chemical analysis.
• Food & Beverage – to check pH levels in water, drinks, brewing, and fermentation.
• Cosmetics & Skincare – to test soap, lotions, shampoos, and other formulations.
• Aquariums & Gardening – to measure water and soil pH for healthy growth.
• Education & General Use – ideal for science projects and classroom demonstrations.
How it works:
Simply dip the strip into the solution, wait a few seconds, and compare the resulting color change with the included pH color chart to determine the pH value.
Features:
• Wide range: usually 1–14
• Fast and easy to use
• Clear color scale for accurate comparison
• Suitable for water-based solutions
How to use our pH test strips
Step 1
Absorb a little of the liquid to be tested, and then drop it onto the test strip.
Step 2
The tested paper will produce color changes one second after contact with the solution.
Step 3
Match colored test strip to color chart within 15s, The value closest to the color on the chart is your pH.
Cautions
the strips can not indicate the Acid or alkali solution when its density was lower than 0.01%.
Test paper should be stored in a dry place to avoid light, and no sour and alkaline air can be stored again.
When using, please do not immerse the pH bar in the test liquid. It can cause the test results to be displayed incorrectly.
The color changes of the test strip need to be matched within 15 seconds.
