Common dissolved oxygen detection methods and their characteristics:

1. Fluorescence sensor:
Advantages: high sensitivity, wide measurement range, high accuracy, real-time monitoring, no sample processing, long life and stability.
Disadvantages: special sensor equipment is required, and the cost is high.

2. Electrochemical sensor (polarography or electrode method):
Advantages: high sensitivity, real-time monitoring, no need for sample processing, and on-site measurement.
Cons: Susceptible to interfering substances, requires regular calibration and maintenance.

3. Oxygen concentration measuring instrument:
Advantages: easy to use, real-time monitoring, no sample processing required.
Disadvantages: narrow measurement range and low accuracy.

4. Needle dissolved oxygen electrode:
Advantages: real-time monitoring, no sample processing, and can be used in the field.
Cons: Sensitive to temperature changes, requires regular calibration and maintenance.

5. Dissolved oxygen measurement method in the bottle (wen bottle method):
Advantages: relatively simple, suitable for laboratory conditions.
Disadvantages: Not suitable for real-time monitoring, requires sample sampling, susceptible to external interference.
