Dissolved Oxygen Sensors and Probes

Dissolved oxygen sensors can be used in a wide variety of applications - surface water, aquaculture, groundwater, wastewater, and more! YSI offers two primary types of dissolved oxygen sensing technologies: optical-based sensors and the Clark electrochemical or membrane-covered electrode. Optical dissolved oxygen (ODO) sensors require no warmup time, so they can be used instantaneously. Additionally, these sensors do not require stirring or water movement for accurate dissolved oxygen measurements.

Electrochemical sensors (galvanic and polarographic) require more maintenance but offer faster response times and lower acquisition costs. To learn more about the measurement of dissolved oxygen, how dissolved oxygen sensors work, the differences between sensors, available DO meters, and which sensor is right for you, visit our resources or consult our lab, environmental, and municipal experts.
