FAQs

Q1: What is a pH electrode?
A1: The pH electrode is also called the pH probe pH sensor. The pH electrode is the part of the pH meter that is in contact with the substance to be measured and is used to measure the electrode potential.

Q2: Why do pH electrodes need to be soaked?
A2: The pH electrode must be soaked before use, because the pH bulb is a special glass membrane with a thin hydrated gel layer on the surface of the glass 
membrane, which can only interact with the H+ ions in the solution under fully wet conditions. the response to. At the same time, after soaking the glass 
electrode, the asymmetric potential can be greatly reduced and tend to be stable.

Q3: What is a reference electrode?
A3: An electrode with a known and constant electrode potential that does not respond to the activity of hydrogen ions in solution is called the reference electrode. Reference electrodes include mercurous sulfate electrodes, calomel electrodes, and silver/silver chloride electrodes. The most commonly used are calomel electrodes and silver/silver chloride electrodes. The role of the reference electrode in the measurement cell is to provide and maintain a  fixed reference potential, so the requirements for the reference electrode are that the potential is stable and reproducible, the temperature coefficient is small, and the polarization potential is small when current flows.

Tips: What is a pH combination electrode?


An electrode that combines a pH glass electrode and a reference electrode is called a pH composite electrode. If the outer shell is plastic, it is called a plastic shell pH composite electrode. The outer shell is glass, it is called a glass pH composite electrode. The biggest advantage of composite electrodes is that they are combined into one and are easy to use. The structure of a pH composite electrode is mainly composed of an electrode bulb, glass support rod, internal reference electrode, internal reference solution, shell, external reference electrode, external reference solution, liquid junction, electrode cap, electrode lead, socket, and so on.
