One kind of popular and cost-effective online pH/ORP controller.

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

“One Dynamic and Two Static” Double Static Ceramics Plates Multi-port Valve is on behalf of another beginning in the field of water treatment control, which can overcome many disadvantages of traditional products in installation.


For complex industrial processes, sewage treatment, water reuse, environmental monitoring, industrial field control, chemical process, thermal detection and discrete control, data transmission control and remote data transmission.

This series of brine valves have overcome the deficiency of the products existing in the market. It can not only protect water injection and check the air, but also can limit the extreme amount of water injection and filter the water running inside. If water injection is too fast, the liquid level inside the brine well will spill out quickly and the injection has to be shut down, which will result in the insufficiency of water inside the brine tank and have bad influence upon the outcome of recycling. This kind of brine valves depends on water pressure to work. It is reliable in working and valuable in extensive employment.

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


Widely used for online measurement of acid&alkali in low concentrations and the low viscosity single-phase fluid of non-trade settlement process.
