Comparison between Electrochemical Dissolved Oxygen Electrode and Optical Dissolved Oxygen Electrode:

Polarographic or primary battery type dissolved oxygen electrode

Test: Dissolved oxygen is consumed during measurement, and the measurement value is unstable.

Correction: The electrode polarization is severe and requires frequent correction, which takes a long time.

Performance: Slow response, poor repeatability, low accuracy.

Lifespan: Regularly replacing the electrode membrane and replenishing the electrolyte result in a short lifespan.

Optical dissolved oxygen electrode

Testing: Using fluorescence technology, it does not consume dissolved oxygen, and the measurement is stable.

Calibration: No polarization, no need for frequent calibration, calibration only takes 2 minutes.

Performance: Response time of 15 seconds, good repeatability, high accuracy.

Lifespan: No electrode film, no electrolyte, lifespan>8000 hours.
