Roll (4.8m), with colour scale, pH 3.8 - 4.1 - 4.4 - 4.6 - 4.8 - 5.1 - 5.4MQuant® pH indicator papers supplied in rolls are perfectly suited for long-term storage, since they are protected against external influences, such as moisture, light, and ambient gases. These pH indicator papers are manufactured by impregnating high-quality filter paper with indicator or mixed-indicator solutions. The paper is always ready to use; it is easily pulled out of the plastic reel and can be torn off in the necessary length. The pH value is measured semi-quantitatively by visual comparison of the colour formed on the paper with the fields of the colour scale.
