DO30G-NN-50-05-PN DISSOLVED OXYGEN SENSOR YOKOGAWA

Description:

The Yokogawa DO30G-NN-50-05-PN Dissolved Oxygen Sensor is a galvanic-type measurement sensor used in liquid analysis systems for continuous monitoring of dissolved oxygen levels in water processes. Commonly installed in wastewater treatment plants, aeration tanks, potable water systems, aquaculture facilities, and environmental monitoring stations. Maintenance teams and system integrators use this part for water quality monitoring, sensor replacement, and ensuring accurate dissolved oxygen measurement in critical process control applications.

Applications:

The Yokogawa DO30G dissolved oxygen sensor is widely used in water and wastewater treatment facilities, including activated sludge processes, aeration basins, and effluent monitoring systems. It is also applied in river monitoring, fish farming, and industrial water treatment where maintaining proper oxygen levels is essential for biological processes and system performance. The sensor provides continuous dissolved oxygen measurement with stable long-term operation and supports integration with Yokogawa analyzers such as FLXA402 and FLXA21 systems.
