The pH electrod installation methods:

1. Side wall installation (*The pH electrode must be at an angle of 15 degrees to the liquid surface. Otherwise, it will affect the normal use of the pH electrode.)
2. Flange mounted at the top
3. Pipe installation
4. Top installation
5. Submersible installation
6. Flow-through installation
Tips: PTFE electrode dosing system
- The electrode should be installed in the bypass beside the main pipe, and a valve should be installed at its front end to control the flow velocity. The flow shall be as small as possible, generally, as long as the outlet has a stable aqueous solution drops. Electrodes should be installed vertically and go deep into active water, and the water outlet should be higher than the water inlet to ensure that the electrode is completely immersed in the solution.
- The electrode should be calibrated before installation.
- As the measurement signal is a weak electrical signal, its acquisition cable should be independent and avoided to be connected in a same cable connector or terminal with the power line and control line, so as to avoid interference or breakdown of measuring units.
- When measuring cables need to be lengthened, please choose to customize the length or contact customer service (more than 15m).
