pH Indicator Dispenser

pH Indicator Dispenser

Indicator paper supplied in plastic dispenser containing 5 meters of 8 mm wide test strip. A colour chart is provided on the side of each dispenser.

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 causes the paper 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 packages that pH paper comes in often includes a color-coded scale indicating the pH that something has when the paper turns a certain color. For instance, if the paper turns a dark greenish-blue, the pH may likely be around 11 to 14.

Please select form the available ranges pH 1 to 11 or pH 1 to 14.
