Optical Dissolved Oxygen Sensor – Industrial DO Probe with 4–20mA & RS485 Output
High-stability optical dissolved oxygen (DO) sensor designed for long-term monitoring in aquaculture, water treatment, and environmental applications. Low maintenance with dual output for seamless system integration.
This optical dissolved oxygen sensor is a robust, low-maintenance solution for accurate DO measurement in water-based applications. Using optical (luminescence-based) sensing technology, it eliminates the need for electrolyte replacement and reduces calibration frequency compared to traditional electrochemical probes.
Designed for continuous deployment, the sensor provides stable and reliable dissolved oxygen readings across a wide range of operating conditions. It is well suited for aquaculture systems, wastewater treatment, environmental monitoring, and industrial water processes.
The probe features a durable 316L stainless steel construction and IP68 protection, enabling long-term submersion in harsh environments. With both 4–20mA and RS485 (Modbus) outputs available simultaneously, it integrates easily into PLCs, RTUs, SCADA systems, and cloud-based monitoring platforms.
Its low power consumption and wide operating range make it ideal for remote installations and IoT-based water quality monitoring solutions.
