Basic Principle of pH Electrode
1. The polymer filling makes the reference junction potential very stable.
2. The diffusion potential is very stable; large-area diaphragm surrounds the glass diaphragm bubbles, so that the distance from the reference diaphragm to the glass diaphragm is near and constant; the ions diffused from diaphragm and the glass electrode quickly form a complete measurement circuit to respond quickly, so that the diffusion potential is not easy to be affected by the outside flow rate and is thus very stable!
3. As the diaphragm adopts the polymer filling and there is small and stable amount of overflowing electrolyte, it shall not pollute the measured pure water.
Therefore, the above-mentioned features of the composite electrode make it ideal for measuring PH value of high-purity water!

Features of PH Electrode
| ● It adopts the world-class solid dielectric and a large area of PCE liquid for junction, difficult to block and |
| Convenient 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 40 |
| meters free of interference. |
| ● There is no need for additional dielectric and there is a little amount of maintenance. |
| ● High measurement accuracy, fast echoing 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. |
Application filed: Medicine, chlor-alkali chemicals, dyes pigments, pulp and paper, intermediates, fertilizers, starch, water and environmental protection industries, high purity water measurement.
