PH/ORP-9900 Water Quality Test PH/ORP Controller
On-line analysis and process control of the oil refining, metallurgy,chemical synthesis industry process;

On-line analysis and process control of the oil refining, metallurgy,chemical synthesis industry process;

Applicable to all kinds of small and medium-sized single-stage, double-stage reverse osmosis control system. With simple operation, complete measurement and configuration, highly integrated system

RF double tank floating bed plane multi-way valve, realized tow tank softening at the same time and regenerating alternate, integrated with brine jet device and brine flow meter and brine electric valve, with soft water flow meter, guarantees the water softening , the water regenerating and water filling to salt box, Complete according to the set volume.as long as the factory according to the raw water hardness set corresponding operation parameters, can always guarantee the stable operation of the equipment, guarantee the softened water and salt consumption.

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

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

ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument.

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.

Salt and water savings by using 100% capacity of the tank in service before switching to the second tank
Regenerates immediately when needed for continuous soft water
Corrosion-free fiber-reinforced polymer valve body


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.
