Dissolved Oxygen Sensors

Dissolved oxygen probes are essential instruments for measuring oxygen concentration in liquids, playing a crucial role in various industrial and scientific applications.

Sensor Types:

• Electrochemical: They use redox reactions to generate a signal proportional to the oxygen present.
• Optical: They use fluorescence principles to measure dissolved oxygen, offering advantages such as fast response times and greater long-term stability.

Measuring Ranges:

Ranges vary by model and application, but typically range from 0 mg/L to 20 mg/L, with an accuracy of ±0.05 mg/L.

Maintenance and Calibration:

Maintenance varies depending on the type of sensor; optical models typically require less maintenance than electrochemical ones. Periodic calibration is essential to maintain measurement accuracy.

In summary, dissolved oxygen probes are essential tools for monitoring and controlling processes that require accurate dissolved oxygen measurements, such as in water treatment, biotechnology processes and aquaculture.
