RS485 Luminescent Dissolved Oxygen Probe Requires No Calibration

RS485 Luminescent Dissolved Oxygen Probe Requires No Calibration

The DRFN’s luminescent Dissolved Oxygen probe can be widely used in urban sewage treatment, industrial wastewater treatment, surface water monitoring, sea water monitoring, fish farming, aquarium, drinking water, etc. Dissolved Oxygen monitoring throughout wastewater treatment, and particularly in the activated sludge phase, is key to effective and efficient treatment.

Measuring Principle Of The Luminescent Dissolved Oxygen Probe

The luminescent Dissolved Oxygen probe covers the detection head(luminescent membrane cap) with a layer of luminescent material. The LED light source in the sensor emits blue light to the fluorescent material on the surface of the head (luminescent Membrane cap). The luminescent material is excited and emits red light. The higher the dissolved oxygen concentration, the shorter the time from emitting blue light to red light. Using the correlation between red light release time and dissolved oxygen concentration (release time), the dissolved oxygen analyzer calculates the dissolved oxygen concentration in the medium.

Advantages of The Luminescent Dissolved Oxygen Probe

• The DRFN OPD70 LDO probe can meet various works without calibration.

• The sensor is equipped with digital communication Modbus RS485 protocol.

• Compact and light, the LDO probe can be conveniently connected to online transmitters, DTUs, and portable instruments.

• The protection grade of the LDO sensor is IP68, it can work continuously and stably under water for a long time.
• No need to consume oxygen, especially at very low oxygen concentration for accurate measurement.
