Q: How does an optical dissolved oxygen analyser work?

A: Optical DO analysers use fluorescent quenching technology. A sensor emits blue light to excite a fluorescent coating, and oxygen concentration is measured based on the phase shift of the returning red light. This method eliminates membrane and electrolyte maintenance.

Q: What are the advantages of optical DO analysers over traditional Clark electrode sensors?

A: Optical dissolved oxygen analysers require no electrolyte solution or membrane replacement. They provide faster response times, reduced drift, and perform better in low-oxygen or turbulent conditions compared to electrochemical sensors.

Q: Can optical DO analysers measure turbidity simultaneously?

A: No, optical dissolved oxygen analysers specifically measure oxygen levels. For turbidity analysis, a separate turbidity analyser using nephelometric principles (light scattering measurement) is required.

Q: How often should optical dissolved oxygen sensors be calibrated?

A: Most optical DO analysers need calibration every 3-6 months under normal use. Their stable sensing technology maintains accuracy longer than traditional sensors, but regular validation against known standards is recommended.

Q: Are optical DO analysers suitable for wastewater treatment applications?

A: Yes, optical dissolved oxygen analysers excel in wastewater treatment. Their design resists fouling, functions in high-solids environments, and provides reliable measurements for aeration control without membrane maintenance.
