Dip the test strip into the sample liquid, quickly remove it and compare the pH value with a color chart. Since the launch of Micro Essential Laboratories (MEL) in 1934, MEL has gained experience with the dyes it uses and has made efforts to expand the range of uses for pH measurement, resulting in the establishment of the Hydrion brand. Today, MEL's quality, accuracy, and reliability have set the standard for quality. For unknown samples, we recommend measuring the pH value beforehand to be on the safe side. This is a roll type that allows you to freely decide the length of the test paper. pH measurement range: 1 to 14 Size: 5.5mm x 4.57m Roll type with dispenser Quantity: 1 roll *If the sample is expected to be a strong acid, please use it with due consideration to safety.
