The Laboratory Dissolved Oxygen Sensor is specialized in quantifying the amount of oxygen dissolved in a liquid medium. Using either galvanic or optical methods, it accurately measures this crucial parameter. Galvanic sensors rely on a chemical reaction between oxygen and electrodes to generate an electric current, while optical sensors use fluorescence quenching by oxygen molecules. This sensor is vital in aquaculture to maintain optimal oxygen levels for fish survival and growth. In wastewater treatment plants, it helps monitor the efficiency of aerobic processes. It has a highly sensitive membrane that allows for precise oxygen detection, even in trace amounts. The dissolved oxygen sensor is designed to be easily calibrated, ensuring consistent and reliable results over time. Its ability to work in both static and flowing liquid systems makes it versatile for different laboratory setups.
