CS4762CD Dissolved Oxygen Sensor
Unlike traditional electrochemical probes, the modern fluorescence-based dissolved oxygen (DO) sensor represents a revolutionary, membrane-free approach to oxygen measurement. Its operation relies on the principle of luminescence quenching rather than electrochemical reduction.
The core of the sensor is a specially designed optode or sensing spot, coated with a luminescent dye (often a ruthenium complex) embedded in a oxygen-permeable polymer matrix. A blue or UV light source from the instrument excites this dye, causing it to emit red light. When oxygen molecules are present, they interact with the excited dye molecules, quenching (reducing) the intensity and duration (lifetime) of this emitted luminescence. The degree of quenching is precisely and proportionally related to the partial pressure of dissolved oxygen. The instrument measures either the intensity or, more commonly and reliably, the phase shift or lifetime of the fluorescence, which is inherently more stable and less prone to drift. -

CS4760CD Dissolved Oxygen Sensor
technology offers significant advantages over conventional Clark-type electrodes. It requires no electrolytes, membranes, or periodic polarization, eliminating routine maintenance like membrane replacement and electrolyte refilling. It is unaffected by flow rate or stirring speed, provides a much faster response time, and does not consume oxygen during measurement, making it ideal for small sample volumes or biological cultures.
Consequently, fluorescence-based DO sensors have become the gold standard in applications demanding high precision, low maintenance, and minimal sample disturbance. They are extensively used in environmental monitoring (long-term deployments in buoys or profilers), wastewater treatment process control, aquaculture, pharmaceutical/bioreactor fermentation, and advanced laboratory research. By offering superior reliability and operational simplicity, they have redefined the landscape of dissolved oxygen analysis.
