PFDO-500 Aquaculture Fluorescence Dissolved Oxygen Online Analyzer

Category:
Optical Water Quality Online Analyzer
PFDO-500 dissolved oxygen online analyzer uses fluorescence method to measure dissolved oxygen, the top of the sensor is covered with a layer of fluorescent substances, when the blue light emitted by the sensor irradiates the fluorescent substances, the fluorescent substances are excited to emit red light, because the oxygen molecules can take away energy (quenching effect), so the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules, and the concentration of dissolved oxygen in the water can be obtained by calculation.

Measurement Principle

PFDO-500 dissolved oxygen online analyzer uses fluorescence method to measure dissolved oxygen, the top of the sensor is covered with a layer of fluorescent substances, when the blue light emitted by the sensor irradiates the fluorescent substances, the fluorescent substances are excited to emit red light, because the oxygen molecules can take away energy (quenching effect), so the time and intensity of the excited red light are inversely proportional to the concentration of oxygen molecules, and the concentration of dissolved oxygen in the water can be obtained by calculation.

Key Features
  • The sensor adopts a new oxygen-sensitive membrane with NTC temperature compensation function, and the measurement results have good repeatability and stability;
  • No oxygen consumption is generated during measurement, and there is no flow rate/agitation requirement;
  • Breakthrough fluorescence technology, no membrane and electrolyte, basically maintenance-free;
  • Built-in self-diagnosis function to ensure accurate data;
  • Factory calibration, no calibration required for one year, can be calibrated on site;
  • Digital sensor, strong anti-interference ability, long transmission distance;
  • Standard digital signal output for integration and networking with other devices without a transmitter;
  • The sensor is convenient and fast to install on site, realizing plug and play;
  • Sensor power supply positive and negative reverse connection protection;
  • Sensor RS485 A/B misconnection power protection;
  • With time display, data storage and historical data viewing functions;
  • Optional data wireless transmission module.
Application Scenarios
  • DO online monitoring of various processes such as sewage treatment plant regulation tank, biochemical tank, and effluent;
  • DO online monitoring for waterworks, surface water, water for various industrial production processes, aquaculture, and other industries.
