Principle
In pH measurement, the used electrode is also known as the primary battery. The primary battery is a system,
whose role is to transfer chemical energy into electrical energy. The voltage of the battery is called the electromotive
force (EMF). This electromotive force (EMF) is composed of two half-batteries. One half-battery is called the
measuring electrode, and its potential is related to the specific ion activity; The other half-battery is the reference
battery, often called the reference electrode, which is generally interlinked with the measurement solution, and
connected to the measuring instrument.

Features
1. It adopts the world-class solid dielectric and a large area of PCE liquid for junction, difficult to block and easy maintenance
2. Long-distance reference diffusion channel greatly extends the service life of electrodes in the harsh environment
3. A new design of glass bulb increases the bulb area, prevent bubble formation interference within the buffer, makes the measurement more reliable.
4. It adopts PPS/PC casing and the upper and lower 3/4NPT pipe thread, so it is easy for installation and there is no need of
the jacket, thus saving the installation cost.
5. The electrode adopts the high-quality low-noise cable, which makes the signal output length less than 20 meters free of interference.
6. There is no need for additional dielectric and there is a little amount of maintenance.
7. High measurement accuracy, fast echoing and good repeatability.
8. Reference electrode with silver ions AG/AgCL
9. Proper operation shall make service life longer.
10. It can be installed in the reaction tank or pipe laterally or vertically.
11. The electrode can be replaced by a similar electrode made by any other country.
