CS4800 Dissolved Oxygen Electrode
DO electrodes are indispensable across numerous fields. In environmental monitoring, they assess the health of rivers, lakes, and oceans, as oxygen levels are a key indicator of water quality and ecosystem viability. In wastewater treatment plants, they are crucial for optimizing the biological treatment process by ensuring sufficient oxygen for microbial activity. Furthermore, they play essential roles in aquaculture to maintain healthy conditions for fish, in the food and beverage industry for process and quality control, and in pharmaceutical and biochemical research for monitoring cell cultures and fermentation processes.
Modern DO electrodes are often coupled with advanced meters for temperature and salinity compensation, ensuring high accuracy and reliability. Despite the emergence of optical fluorescence-based sensors, the electrochemical DO electrode remains widely valued for its robustness, proven performance, and cost-effectiveness in diverse laboratory and industrial settings. -
CS4802 Dissolved Oxygen Electrode
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. -
