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.
