Principle Introduction:

The dissolved oxygen sensor adopts advanced fluorescence quenching technology. When the blue light emitted by the sensor shines on the fluorescent substance on the fluorescent cap, the fluorescent substance is excited and emits red light,

Due to the ability of oxygen molecules to carry away energy (quenching effect), the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules. By calculation, it can be concluded that water

The concentration of dissolved oxygen.

Instrument features:

At the bottomThe sensor adopts a new type of oxygen sensitive membrane and comes with its ownNTCTemperature compensation function, with good repeatability and stability of measurement results;

At the bottomThere will be no oxygen consumption or flow rate during measurement/Stirring requirements;

At the bottomBreakthrough fluorescence technology, without membranes or electrolytes, requiring minimal maintenance;

At the bottomFactory calibration, no calibration required for one year, can be calibrated on-site;

At the bottomDigital sensors with strong anti-interference ability and long transmission distance;

At the bottomStandard digital signal output, which can be integrated and networked with other devices without a transmitter

Typical applications:

lOnline monitoring of dissolved oxygen (DO) in various processes such as regulating tanks, biochemical tanks, and effluent in sewage treatment plants;

lØDO online monitoring for industries such as waterworks, surface water, water used in various industrial production processes, aquaculture, etc
