The DO-B903 is designed as a benchtop structure for easy placement on the laboratory bench, featuring high accuracy, stability, and ease of operation. The Benchtop Dissolved Oxygen Meter measures the oxygen content of a liquid through a sensor and displays the results on the instrument's digital display for real-time monitoring and recording. This type of dissolved oxygen meter is usually used in water quality monitoring, environmental science research, aquaculture, and other fields and can provide accurate dissolved oxygen data.
