c. Online analysis and drug maintenance of the process for environmental monitoring, waste water treatment, water purification ;
d. Industry of the people’s livelihood, such as municipal water treatment, circulating cooling water, swimming pool management, scientific and technological agriculture;
e. The biological fermentation, industrial coating, chemical process experimental study.

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

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.

BSQ-MINI is widely used in metallurgical manufacturing, electric power, light industry, textile, water treatment equipment, tap water pipe network and scientific research and other industrial sectors.

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

FLECK control valve 5600 softening water equipment generally uses fixed bed downstream
regeneration, the working process is operation, backwashing, regeneration, replacement,
positive washing, salt tank water injection.


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.
