PH8012 Industrial Composite Sewage PH Sensor
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. |
