KFDO310 Online Fluorescence Dissolved Oxygen Sensor No Electrolytes No Polarization No Need To Consume Oxygen

1.Principle

KFDO310 integrated on-line fluorescence dissolved oxygen sensor is designed and made based on the quenching principle of excited fluorescence of specific substances in physics. The blue light from the light-emitting diode illuminates the fluorescent material on the inner surface of the fluorescent cap. The fluorescent material on the inner surface is excited and emits red light. By detecting the phase difference between the red light and the blue light, and comparing it with the internal calibration value, the concentration of oxygen molecule can be calculated, and the final value can be output by temperature automatic compensation.

2.Feature

No electrolytes, no polarization

No need to consume oxygen, not affected by the flow rate

Built-in temperature sensor, automatic temperature compensation

Free from chemicals like sulfides

Small drift, fast response, more accurate measurement

Maintenance-free, long service life, lower use cost

Fluorescent caps are easy to replace

RS-485 interface, Modbus-RTU protocol

Dissolved Oxygen Measurement Methods

measuring_dissolved_oxygen_3_methods

Dissolved oxygen can be measured by colorimetry, a sensor and meter or by titration.

There are three methods available for measuring dissolved oxygen concentrations. Modern techniques involve either an electrochemical or optical sensor. The dissolved oxygen sensor is attached to a meter for spot sampling and laboratory applications or to a data logger, process monitor or transmitter for deployed measurements and process control.

 

The colorimetric method offers a basic approximation of dissolved oxygen concentrations in a sample. There are two methods designed for high-range and low-range dissolved oxygen concentrations. These methods are quick and inexpensive for basic projects, but limited in scope and subject to error due to other redoxing agents that may be present in the water 27.
