PG13.5 Wide Voltage 5-40V RS485 Digital Fluorescence Dissolved Oxygen Sensor
Aquaculture Wide Voltage 5-40V RS485 Digital Fluorescence Dissolved Oxygen Sensor Fish Farming DO Probe
Overview
The fluorescence-based dissolved oxygen sensor operates on the principle of fluorescence quenching to detect dissolved oxygen in water. It requires no electrolyte and no consumables, resulting in low maintenance costs over long-term use. Equipped with an NTC10K temperature compensation element, it automatically eliminates measurement deviations caused by temperature changes, ensuring stable and accurate data.
With digital RS485 MODBUS RTU output, it can be directly connected to PLCs and online water quality monitoring devices. The entire probe is made of 316L stainless steel, offering excellent corrosion resistance. The measuring section is rated IP68, supporting long-term submerged online monitoring. It is widely used for real-time dissolved oxygen measurement in natural water bodies, water supply systems, and wastewater treatment.
