What is a Digital pH meter?

A digital pH meter is a machine that measures pH. Measure by inserting the electrodes of the device directly into the sample. This device is easy to handle and affordable, so it is used in a variety of fields and purposes. Most digital pH meters use a glass electrode method as the measurement method. Other pH measurement methods include methods using indicators such as litmus test paper, hydrogen electrode method, quinhydrone electrode method, and antimony electrode method, but the glass electrode method is safer and more accurate than other measurement methods. , The reproducibility is also high.

Application of Digital pH meter

pH is one of the indexes showing the environment of water bodies such as rivers and lakes, and is one of the indexes that influence the pretreatment conditions and analysis conditions of samples in chemical analysis. Since pH also affects the progress of chemical reactions, it may be controlled at the manufacturing site. Digital pH meters are used in various places because pH needs to be accurate and easy to measure in these various fields. The pH meter has different electrode liquid drop parts depending on the application, and it is a porous type (usable for general aqueous solutions) and a sleeve type (used for viscous samples and samples with a high content of water-insoluble substances). It can be divided into. It is necessary to select the optimum pH meter in consideration of the characteristics of the sample and the container.
