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.

Plays a central role in optimizing the aeration process, helping reduce energy consumption while ensuring effective biological degradation of pollutants. Can be deployed in SBR, MBBR, and activated sludge tanks.
Critical for aquatic animal health and survival. The fast response and high precision allow operators to manage pond or tank oxygenation in real time, improving fish yield and feed utilization efficiency.
Essential in bioreactors used for fermentation or cell culture where oxygen must be maintained within strict thresholds to support optimal microbial or cellular metabolism.
Supports government agencies and researchers in measuring oxygen content in lakes, reservoirs, and rivers. Provides valuable data for assessing ecosystem health and identifying pollution events.
Monitors DO levels during fermentation and bottling, where excess oxygen can lead to spoilage or altered taste.
Finds value in cooling water systems, industrial wastewater recycling, and marine ecosystem studies.
