CL-9500 residual chlorine controller is a new controller. This meter has a high degree of intelligence and flexibility. It can measure Residual chlorine value and temperature at the same time. It is widely used in urban sewage treatment plants, water supply and other industries and can continuously measure the Residual chlorine value of solution.


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;


FLECK control valve 5600 softening water equipment generally uses fixed bed downstream
regeneration, the working process is operation, backwashing, regeneration, replacement,
positive washing, salt tank water injection.
