PEHANON® pH Indicator Strips, Electron Microscopy Sciences
Test Papers pH Indicator Papers and Test Strips
Series of pH indicator papers where the indicator and color scale are combined on a single strip.

They permit a fast, convenient and accurate pH value determination since they eliminate the necessity to compare color against a separate scale. This presentation also permits the pH measurement of colored solutions and suspensions, since the color of the test solution acts on the comparison scale in the same manner as on the indicator field. The PEHANON® series covers the entire pH range from 0 to 12 with one universal paper and 13 narrow ranges which overlap to permit the user utmost selectivity for the range suited to each particular need. The indicator zone (unprinted field) is in the center of the strip, the comparison fields above and below same. The strip is submerged in the solution for about three seconds so that all colors zone are wetted whereby the center field changes color according to the pH value of the solution and is then compared against the color filed bearing the corresponding pH value imprint. An invisible hydrophobic barrier just above the top color field prevents capillary action of the test solution beyond that point and corrosive, toxic or otherwise noxious liquids to not come in contact with fingers which remain clean and dry.

Packaging: Strips are packed in a plastic box, containing 200 strips.
