MD Series Dissolved Oxygen Sensor with High Accuracy Polarographic Probe

Description

Analog dissolved oxygen sensors, also known as membrane-covered polarographic oxygen electrodes, are crucial for accurately measuring dissolved oxygen (DO) levels in various aqueous environments. These sensors, featuring a silver anode and a platinum cathode, are embedded within an insulating material. A potassium chloride electrolyte solution is separated by a permeable membrane that allows selective passage of oxygen molecules. This design ensures cost-effectiveness and enhances the sensors' applicability across diverse industries, making them indispensable tools for environmental monitoring, industrial processes, and scientific research.?
