Online dissolved oxygen detector is an online intelligent dissolved oxygen detector produced by our company with the introduction of foreign technology, using imported components and dissolved oxygen film head, based on the latest polarographic analysis technology, and advanced production technology and surface attachment technology. The use of this series of advanced analytical techniques to ensure long-term stability, reliability and accuracy of the instrument. With Chinese menu operation, 485 communication and other functions. It can be widely used in chemical fertilizer, metallurgy, environmental protection water treatment engineering, pharmaceutical, biochemical, food, aquaculture and tap water and other solutions for continuous monitoring of dissolved oxygen value.


Widely used for electric power,electronics,metallurgy,petrochemical,pharmaceutical ,food and Ā beverage,environmental protection field.


DR20\40\50\20T\40T Soften valve series is floating bed, all appearance and geometric parameters and parts is the same as the corresponding GR20\40\50\20T\40T, floating bed has a good water quality, to adapt high hardness of the raw water, configuration swap tank should be fine and high, runing velocity in the 30-60 m/h, but resin filling rate must be above 90%, being stable working pressure,The floating bed is not suitable for frequent starting and changing water consumption.


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;


Meter, time clock dual mode. In flow mode, the internal flow transmitter realizes the function of setting water volume as required. After setting regeneration water volume and cleaning water volume of exchange tank, the period of softening water amount (ton) according to the hardness of the raw water, each station decreases to “0” according to the set value, and stops decreasing and maintains when the water is out of service or no water.


1) Working Position : Service->Back Wash->Brine and slow Rinse->fast rinse->Refill softened water->service.
Downflow type .Working Position : Service->Back Wash->Brine and slow Rinse->fast rinse->Refill->service.
2) Using ceramic moving valve disk, small rotation torque.
3) Abrasion resistance of sealing surface, outstanding and long-lived deal.
4) It could be operated with pressure directly.


Fully adjustable, 5-cycle control delivers upflow backwash, downflow brining, slow rinse, rapid rinse, brine refill, and downflow service
Time-tested, hydraulically-balanced piston, seal and spacer, controls service flow and regeneration
Non-corrosive, fiber-reinforced polymer construction
Excellent flow rates (19 GPM continuous, 24 GPM peak)
Backwash capacity handles tanks up to 16″ diameter for softener, andĀ filter
