pH Test Paper - 80 Strips
pH Test Paper (Universal pH Paper) - 80 Strips
A pH test strip is a strip of litmus paper with which you can measure the pH value of a liquid. The substance in the paper allows it to show a different colour at different acidities. This is determined by dipping part of the paper into a solution of interest and watching the color change. The package includes a color-coded scale indicating the pH that a solution has when the paper turns a certain color. For instance, if the paper turns a dark greenish-blue, the pH is likely be around 11 to 14.
The test strip color change must be matched with the pH scale color chart no longer than 15 seconds after it has been submerged to ensure accurate results. Quick and easy to use it provides reliable and accurate pH readings. With distinct color PH scale for result comparisons it is appropriate for testing alkaline or acid level of any liquid. This is a great product to have in every lab and at home to measure and inspect water quality, saliva, soil, aquariums etc, as well as science education.
