DOG-209FYDtypefluorescenceFrench sensor
Measurement principle:
The dissolved oxygen analyzer uses fluorescence method to measure dissolved oxygen. The top of the sensor is covered with a layer of fluorescent substance. When the blue light emitted by the sensor shines on the fluorescent substance,Fluorescent substances emit red light when excited. Due to the quenching effect, oxygen molecules can carry away energy, so the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules. The concentration of dissolved oxygen in water can be calculated.
mainFeatures:
- The sensor adopts a new type of oxygen sensitive membrane and comes with its ownNTCTemperature compensation function, with good repeatability and stability of measurement results;
- There will be no oxygen consumption or flow rate during measurement/Stirring requirements;
- Breakthrough fluorescence technology,No membrane or electrolyteBasically no maintenance is required;
- Built in self diagnosis function to ensure accurate data;
- Factory calibration, no calibration required for one year, can be calibrated on-site；
- Digital sensors with strong anti-interference ability and long transmission distance;
- Standard digital signal output, which can be integrated and networked with other devices without a controller;
- The on-site installation of sensors is convenient and fast, achieving plug and play functionality.
- The regulating tank, biochemical tank, effluent and other process of sewage treatment plantDOOnline monitoring;
- Water treatment plants, surface water, water used in various industrial production processes, aquaculture and other industriesDOOnline monitoring.
