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.


Turbidity is the expression of suspended objects in water to the degree of obstruction of light transmission. This product uses RS485 interface to communicate with the digital sensor, high data accuracy, strong anti-interference, can directly control the digital sensor calibration and automatic cleaning and other functions.


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;

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

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

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

Digital Laser Turbidity online analysis sensor,It can be used for on-line monitoring of water quality in different water bodies such as waterworks and membrane filtrate,The sensor internally completes all measurement calculation compensation
