DX-DO3000 Optical Dissolved Oxygen Analyzer Precision Monitoring for Wastewater Aquaculture and Bioprocess Applications

The DX-DO3000 Online Dissolved Oxygen Meter from Wuxi Daoxin Technology is an advanced instrument designed for accurate, real-time monitoring of dissolved oxygen (DO) levels in a wide variety of industrial and environmental applications. Utilizing state-of-the-art luminescent optical technology, the sensor provides fast and reliable readings without the need for membranes or electrolytes, reducing maintenance frequency significantly.

With a measurement range of 0–20 mg/L and a high resolution of 0.01 mg/L, the DX-DO3000 ensures precision even in low-oxygen environments. Its built-in automatic temperature compensation (ATC) system adjusts readings based on real-time thermal conditions, ensuring consistency across a wide temperature range of 0 to 80°C.

The sensor housing is built to resist corrosion and biofouling, making it suitable for harsh environments such as wastewater and aquaculture systems. Signal outputs include 4-20mA and RS485 with Modbus RTU protocol, supporting seamless integration with modern SCADA and control platforms. Installation options include immersion or flow-through assemblies, with flange mounting available.

The DX-DO3000 is ideal for critical applications where dissolved oxygen levels directly impact safety, efficiency, and compliance:

• Municipal wastewater treatment: Optimizing aeration processes in biological treatment tanks
• Aquaculture and fish farming: Monitoring DO to prevent oxygen stress and ensure optimal growth conditions
• Biochemical reactors for pharmaceutical manufacturing: Precise DO maintenance for biological processes
• Brewery fermentation, lake and river oxygen profiling, environmental monitoring
• Seawater oxygen assessment for marine studies

Thanks to its anti-pollution design and minimal maintenance requirements, the DX-DO3000 performs reliably even in long-term deployments.
