Typical applications • Widely used in thermal boiler deaerator water and large and medium-sized industrial boiler feed water; • Operational supervision of reactor Primary circuit, secondary circuit circuits and condensate system; • On-line analysis of dissolved oxygen in circulating water of heat exchange system; • Deaeration control of marine fresh water system, thermal system and…


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;


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.


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.
