Measurement Principle:
The online dissolved oxygen analyzer uses the fluorescence method to measure dissolved oxygen. The sensor tip is coated with a fluorescent substance. When the blue light emitted by the sensor irradiates the fluorescent substance, it becomes excited and emits red light. Since oxygen molecules can carry away energy (quenching effect), the duration 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 through this process.
Features:
l The sensor uses a new oxygen-sensitive membrane with built-in NTC temperature compensation, ensuring good repeatability and stability of measurement results;
l No oxygen consumption during measurement, no flow rate/agitation requirements;
l Breakthrough fluorescence technology, no membrane or electrolyte, virtually maintenance-free;
l Built-in self-diagnostic function to ensure data accuracy;
l Factory calibrated, no need for calibration for one year, field calibration possible;
l Digital sensor with strong anti-interference capability and long transmission distance;
l Standard digital signal output, enabling integration and networking with other devices without a transmitter;
l Sensor installation on-site is convenient and quick, enabling plug-and-play;
l Sensor reverse polarity protection for power supply;
l Sensor RS485 A/B terminal misconnection power protection.
Typical Applications:
l Online DO monitoring in various processes of wastewater treatment plants, such as adjustment tanks, biochemical tanks, and effluent;
l Online DO monitoring in industries such as water treatment plants, surface water, various industrial process water, and aquaculture.
