WSPH1912 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.
