pH8012 Industrial Compound Sewage pH Electrode

Basic Principle of pH Electrode
InpH 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 iscalled the measuring electrode, and its potential is related to
the specific ion activity; the other half-battery is the reference battery, often called thereference
electrode, which is generally interlinked with the measurement solution,and connected to the
measuring instrument.

Features of pH Electrode
Electrode Structure Chart Electrode Wiring Plug
1). It adopts the world-class solid dielectric and a large area of PTFE liquid for junction, non-block and
easy maintenance.
2). Long-distance reference diffusion channelgreatly extends the servicelifeof electrodes in the harsh
environment
3). 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.
3). The electrode adopts the high-quality low-noise cable, which makes the signal output length more than
20meters free of interference.
4). There is no need for additional dielectric and there is a little amount of maintenance.
5). High measurementaccuracy, fast responding and good repeat-ability.
6).Reference electrode with silver ionsAg/AgCL
7). Proper operation shall make service life longer.
8). It can be installed in thereaction tank or pipe laterally or vertically.
9). The electrode can be replaced by asimilar electrode made by any other country.
