PEHANON® pH Test Strips

All-in-one pH test strips are convenient for testing, since the pH indicator and reference colors are all on one strip. Any sample color has the same effect on both the reference colors and the reactive pad, ensuring accurate, unadulterated readings in colored solutions. An invisible hydrophobic barrier just above the top color field prevents capillary action of the test solution beyond. Handle will remain dry and clean regardless of the sample, ensuring safety. Single strips can be used instead of complete packs with color chart to determine pH values. Gradations range from 1-12. Box of 200 strips, 11 x 100 mm.
