The convenience of using pH indicator papers for rapid pH testing has led to widespread use in human medicine, agriculture, industry and environmental applications.

Color Bonded Dye System

Individual plastic support strips carry four different segments of dye-impregnated pH indicator papers. The resulting combination of color differences gives an extremely clear and accurate visual pH value. All the dyes are chemically bonded to the paper and cannot leach into solution, avoiding sample contamination and resultant anomalous pH readings.

Integral Comparison Chart

Each pH test strip has a central segment of indicator dye and, printed alongside, eight or more different color segments marked with corresponding pH values for matching purposes.

The pH test value can be read by direct comparison of the pH test strip color against the integrated color bars. pH indicator strips with integrated comparison bars are excellent for colored solutions so that any changes in the color of the paper stock are automatically disregarded.
