For Plants Oxygen Probe by BOQU

Product Overview

- Model: DOG-209FYD(S) Optical Dissolved Oxygen Sensor from BOQU.

- Optical (fluorescence) dissolved-oxygen probe that measures DO and temperature (DO range 0–20 mg/L or ppm; temperature 0–45°C).

- Rugged, professional design with IP68/NEMA6P protection, standard 10 m cable and materials for fresh- and seawater versions (SUS316L/PVC or titanium).

Product Features

- Fluorescence-based sensing: blue excitation, red emission; DO reading derived from fluorescence lifetime (no oxygen consumed).

- Measurement accuracy: DO ±3%, temperature ±0.5°C; pressure up to 0.3 MPa.

- Communications: MODBUS RS485; automatic air calibration and sample calibration supported.

- Low-maintenance, plug-and-play installation, visual alarm/warning outputs, customizable prompts.

Product Value

- Provides stable, reliable continuous DO monitoring with minimal recalibration and maintenance, reducing operating costs.

- Improves process control and compliance in water and wastewater systems through accurate online data.

- Durable construction and standard digital interface simplify integration into existing monitoring and control systems.

Product Advantages

- Non-consumptive optical method avoids probe oxygen depletion and associated drift—better long-term stability and repeatability.

- Robust design and corrosion-resistant materials (including titanium option) for harsh or seawater environments.

- IP68 protection and simple on-site installation reduce downtime and maintenance effort.

- Industry-standard MODBUS RS485 ensures easy connectivity and data integration.

Application Scenarios

- Sewage and wastewater treatment plants (process monitoring across treatment stages).

- Drinking-water and surface-water quality monitoring.

- Industrial process water and effluent treatment.

- Aquaculture and fish-farming oxygen control.

- Any online dissolved-oxygen monitoring need where reliable, low-maintenance measurement is required.
