A reference electrode is a critical component in electrochemical systems that maintains a constant and reproducible electrode potential. It serves as a stable reference point against which the potential of other electrodes (working electrodes) can be measured accurately. In industrial applications, it ensures precise monitoring and control of electrochemical reactions, such as in pH measurement, corrosion monitoring, and electroplating processes.

定义
A reference electrode is a critical component in electrochemical systems that maintains a constant and reproducible electrode potential. It serves as a stable reference point against which the potential of other electrodes (working electrodes) can be measured accurately. In industrial applications, it ensures precise monitoring and control of electrochemical reactions, such as in pH measurement, corrosion monitoring, and electroplating processes.
工作原理
The reference electrode operates based on the principle of a stable redox couple within a sealed electrolyte solution. It maintains a constant potential by using a reversible electrochemical reaction (e.g., Ag/AgCl or calomel) that is insensitive to changes in the sample solution. This allows it to provide a reliable reference voltage for comparison with other electrodes in the system.
材料
Typically constructed with materials like silver/silver chloride (Ag/AgCl)calomel (Hg/Hg2Cl2)or platinumhoused in a glass or polymer body with a porous junction (e.g.ceramic frit) to allow ionic contact while minimizing contamination.
Lifetime
1-2 years under standard conditions
pH Range
0-14
Junction Type
Ceramic, sleeve, or double junction
Temperature Range
-5°C to 80°C
Potential Stability
±0.1 mV
标准
ISO 10523DIN 19264
