Basic Principle of pH Electrode
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 of PH Electrode
It adopts the world-class solid dielectric and a large area of PTFE liquid for junction, non-block and easy Maintenance.
Long-distance reference diffusion channel greatly extends the service life of electrodes in the harsh environment
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.
The electrode adopts the high-quality low-noise cable, which makes the signal output length more than 20 Meters free of interference.
There is no need for additional dielectric and there is a little amount of maintenance.
High measurement accuracy, fast responsing and good repeatability.
Reference electrode with silver ions Ag/AgCL
Proper operation shall make service life longer.
It can be installed in the reaction tank or pipe laterally or vertically.
The electrode can be replaced by a similar electrode made by any other country.
