Introduction
The water dissolved oxygen sensor is a device that is designed to measure the amount of oxygen dissolved in water. It is a critical tool in many industries, including fisheries, aquaculture, and environmental monitoring. The sensor works by measuring the amount of oxygen in the water using an electrochemical process. This process involves the use of a sensing electrode and a reference electrode, which are placed in the water. As water flows over the sensing electrode, it reacts with the oxygen in the water, creating an electrical current that can be measured. The voltage produced by the sensor is proportional to the concentration of dissolved oxygen in the water. This information can be used to monitor water quality, track changes in environmental conditions, and optimize production in aquaculture and fisheries industries.
