مستشعر الأكسجين المذاب

Q: Can the sensor measure accurately at very low flow or in static water?

Yes.This sensor uses optical fluorescence technology and does not consume oxygen during measurement. The reading is independent of flow velocity, making it highly reliable in low-flow or stagnant conditions.

Q: Will air bubbles affect the dissolved oxygen measurement?

The optical measurement principle is far less sensitive to bubbles than electrochemical sensors. Occasional bubbles do not significantly affect readings, especially in aeration tanks or mixed water environments.

Q: How stable is the sensor for long-term monitoring?

The sensor features minimal annual drift and no electrolyte consumption. Compared to membrane-based DO probes, it maintains accuracy over long periods with significantly reduced recalibration frequency.

Q: كم مرة يحتاج المستشعر إلى صيانة؟

Routine maintenance is minimal.There is no membrane or electrolyte to replace. The fluorescent cap has a long service life and can be easily replaced when required, reducing downtime and maintenance cost.

Q: Is RS485 communication compatible with PLC or SCADA systems?

Yes.The sensor supports RS485 communication, typically using Modbus protocol, allowing seamless integration with PLC, DCS, SCADA, and data logging systems.

Q: Can this sensor be used in harsh wastewater environments?

Absolutely.With an IP68-rated housing and 316L stainless steel + PPS construction, the sensor is designed for continuous submersible operation in corrosive, high-humidity, and industrial wastewater conditions.

Designed for continuous dissolved oxygen monitoring in water and wastewater processes, this optical dissolved oxygen sensor eliminates the limitations of traditional membrane-based probes. With no electrolyte, no oxygen consumption, and no flow dependency, it delivers stable, accurate measurements even in low-flow or static conditions.

It is especially suitable for applications where long-term stability, low maintenance, and reliable digital communication are critical.

Why Optical Dissolved Oxygen Measurement

Traditional electrochemical DO sensors require membranes, electrolytes, and frequent maintenance. This optical dissolved oxygen sensor adopts fluorescence measurement technology, providing a fundamentally different approach:

No membrane, no electrolyte, no polarization
عدم استهلاك الأكسجين أثناء القياس
Stable readings independent of flow velocity
Longer service life with significantly reduced maintenance cost

This makes it ideal for unattended operation and harsh field environments.
