Product Description

Wuxi Daoxin Technology's DX-DO3000 Online Dissolved Oxygen Analyzer is a professional-grade environmental monitoring instrument, purpose-built for long-term deployment in natural water bodies such as rivers, lakes, reservoirs, and wetlands. It supports both luminescent (optical) and membrane-based sensing principles, providing flexibility to meet the diverse demands of field monitoring applications.

The luminescent sensor uses optical fluorescence technology, which requires no membrane or electrolyte and offers a long service life with minimal maintenance. With a resolution of 0.01 mg/L and accuracy up to ±1% FS, the analyzer delivers highly precise readings, essential for detecting subtle oxygen fluctuations linked to ecological health or pollution events.

Its automatic temperature compensation (0 -80°C) ensures accurate measurements across varying climates and seasons. The wide operating temperature range (-10 to 60 °C) and corrosion-resistant housing make it ideal for harsh outdoor deployments, including unattended field stations and buoy-mounted installations.

The analyzer is compatible with 4-20mA and RS485 (Modbus RTU) communication, allowing for seamless integration into environmental telemetry platforms, SCADA systems, or government-managed water quality databases. It supports solar-powered operation when connected to external DC24V sources, making it suitable for remote and off-grid areas.

Applications

Surface water quality monitoring programs - Provides continuous dissolved oxygen data for real-time assessments of water body health and early warnings for hypoxia, eutrophication, or organic pollution.
Rivers and streams - Assesses oxygen stratification, monitors impact of upstream discharges, and tracks seasonal changes affecting aquatic life.
Lakes and reservoirs - Supports vertical profiling through submersible deployment to track oxygen depletion in bottom waters.
Urban stormwater outfalls - Monitors DO levels in runoff channels and retention ponds to detect illicit discharges and assess pollution loads.
Environmental research and academic field studies - Offers long-term, stable measurements needed for ecological modeling and habitat conservation planning.
