This series instruments are widely used for online pH/ORP monitoring in environment protection water treatment, pure water treatment, industrial process and so on.

1) Working Position : Filter->Back Wash->Fast Rinse->Filter
2) Using ceramic moving valve disk , small rotation torque
3) Abrasion resistance of the sealing surface, outstanding and long-lived deal.
4) It could be operated with pressure directly.




Fluorescence quenching principle, no need for internal filling, no oxygen consumption, and easy maintenance;
The service life of the fluorescent membrane cap is more than one year (under ideal conditions);
Original altitude, atmospheric oxygen partial pressure, temperature compensation, to improve the authenticity of the data;

Incorporates 2 time-tested, hydraulically-balanced pistons to independently pilot service flow and regeneration
For use with single or multiple tank systems
