The pH electrode is often used when you use a pH meter for measurement. At the same time, there are many types of pH electrodes. Next, I will take you to understand the classification of pH electrodes according to their uses.
Category 1: Molded case PH composite electrode for routine use, gel KCL, no need to supplement, especially suitable for on-site use; not suitable for high temperature and corrosive solutions, and long-term continuous testing;
Category 2 : Glass PH composite electrode is used for precise PH testing, not suitable for viscous solutions;
Classification 3 : For precise pH testing, it can be used in turbid liquid and colloidal solution;
Category 4 : For precise pH testing, it can be used in liquids with low temperature and low ionic strength
Category 5 : Used in liquids with high temperature and strong acids;
Category 6 : Composite electrodes with automatic temperature compensation;
Classification 7 : It is suitable for the test of flat objects (such as skin, paper, etc.), colloidal substances (such as cheese), and trace solutions.
The heart of an electrochemical meter is the electrode. For example, pH meter, pH electrode is very important. The classification of pH electrodes has many concepts according to different classification methods.
According to the function classification of pH electrodes, there are: low-resistance pH electrodes, high-temperature pH electrodes, strong acid pH electrodes, strong alkali pH electrodes, and pressure-resistant pH electrodes.
