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

BSQ-2019 Water Quality Analyzer can be widely used in metallurgical manufacturing, electric power, light industry, textile, water treatment equipment, tap water pipe network and scientific research and other industrial sectors.

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


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.

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

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.

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

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

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