dissolved oxygen meters

Dissolved oxygen meters are devices used to measure the amount of oxygen dissolved in water, which is vital for aquatic life and water quality. They often work by sending a small electrical current through a sensor that reacts with oxygen, producing a reading that indicates how much oxygen is present. This measurement helps assess the health of ecosystems, monitor pollution levels, and ensure water is safe for organisms like fish. Modern meters are precise, quick, and easy to use, providing critical data for environmental monitoring and water management.
