    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.
