PH8022 Industrial Pure Water PH Sensor
Basic Principle of pH Electrode
- The polymer filling makes the reference junction potential very stable.
- 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!
- 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.
