FAQS on optical dissolved oxygen analyser

Q: What is an optical dissolved oxygen analyser?

A: An optical dissolved oxygen analyser measures dissolved oxygen (DO) in water using fluorescence quenching technology. It uses a sensor coated with a luminescent material that reacts to oxygen levels. This method avoids the need for electrolytes or membranes used in traditional sensors.

Q: How does an optical DO analyser differ from electrochemical sensors?

A: Optical DO analysers use light-based sensing, while electrochemical sensors rely on chemical reactions. Optical models require less maintenance, as they don’t consume electrodes or membranes. They also provide faster, more stable readings in harsh environments.

Q: Where are optical dissolved oxygen analysers typically used?

A: They are ideal for wastewater treatment, aquaculture, and environmental monitoring. Their durability suits continuous monitoring in turbid or high-salinity water. They are also common in industries requiring minimal sensor upkeep.

Q: What maintenance does an optical dissolved oxygen analyser need?

A: Routine maintenance involves cleaning the sensor tip to prevent biofilm buildup. Calibration every few months ensures accuracy. Unlike electrochemical sensors, they don’t require electrolyte refills or membrane replacements.

Q: How often should I calibrate an optical DO analyser?

A: Calibration frequency depends on usage, but typically every 3–6 months. Some models offer auto-calibration features for consistent accuracy. Always follow the manufacturer’s guidelines for optimal performance.
