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. -

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. -
CS4763 Dissolved Oxygen Electrode
dissolved oxygen (DO) electrode, also known as a Clark-type electrode, is a vital analytical tool for measuring the concentration of oxygen molecules in aqueous solutions. Its operation relies on electrochemical principles. The core component is a gas-permeable membrane, typically made of Teflon or polyethylene, which selectively allows oxygen to diffuse through. Behind this membrane lies an electrochemical cell consisting of a cathode (usually gold or platinum) and an anode (often silver), immersed in an electrolyte solution.
When a polarizing voltage is applied between the electrodes, oxygen molecules that diffuse through the membrane are reduced at the cathode. This reduction reaction generates an electric current that is proportional to the partial pressure of oxygen outside the membrane, following Faraday's law. The current signal is then converted into a DO concentration reading, commonly expressed in milligrams per liter (mg/L) or percent saturation. -
