DX-DO3000 Advanced DO Sensor System Long-Term Oxygen Monitoring For Water Aquaculture And Bioprocessing Sustainability

The DX-DO3000 Online Dissolved Oxygen Meter from Wuxi Daoxin Technology represents a new generation of high-precision industrial DO monitoring solutions. It incorporates cutting-edge luminescent sensor technology, offering fast, stable, and interference-free measurements in real time.

Equipped with a wide measurement range of 0–20 mg/L and a resolution as fine as 0.01 mg/L, the DX-DO3000 provides highly sensitive readings suitable for low-oxygen applications such as wastewater aeration basins or fish farming ponds. The system's accuracy reaches ±1% FS or ±0.1 mg/L, ensuring dependable performance even when oxygen levels fluctuate rapidly.

A major highlight of the DX-DO3000 is its automatic temperature compensation (ATC) system, which adjusts readings based on real-time water temperatures ranging from 0°C to 80°C. This ensures that measurements remain accurate regardless of external conditions. The sensor itself is designed with an anti-fouling optical membrane and is housed in corrosion-resistant 316L stainless steel, making it well-suited for long-term exposure to harsh media.

The system supports dual signal outputs — 4-20mA analog and RS485 digital communication with Modbus RTU protocol — allowing seamless integration with PLCs, DCSs, and remote monitoring systems. It can be powered via either AC 220V or DC 24V, offering installation flexibility.

To accommodate different field setups, the DX-DO3000 supports multiple installation methods, including immersion-type mounting for tanks and flow-through cells for pipeline systems. Flange interfaces are also available, ensuring compatibility with industry-standard mounting points.
