pH Indicator Papers and Test Strips
The pH indicator strips measure phosphate content levels through rapid colorimetric reactions. Narrow, intermediate, or universal range options are ready for immediate quantitative testing and feature different graduated intervals for accurate assessments. After immersing pH indicator strips in solutions and samples, simply match the produced color with the charts provided. Compact litmus paper tests can be carried in the field for on-site testing in addition to testing in the laboratory.
