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.

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

Single stage RO controller used for conductivity monitoring and process program control .


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 and time dual mode, the meter mode, its inflow meter achieved all station can be set according to the water volume demanded , as long as set by the swap of tank volume (L) backwash water and wash water, set cycle running water volume(ton), according to the set value for each station after descending to the switch when the “0”, discontinued or no water stop decreasing and maintain. This series of products have beautiful appearance, high material precision of valve body parts, good strength and high temperature resistance, and the main valve body is connected with metal inserts with good maintainability.

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
