What is Dissolved Oxygen?

Dissolved oxygen (DO) is oxygen gas dissolved in water, essential for aquatic life and a key indicator of water quality. Clean surface water typically contains DO levels close to saturation. However, pollution from organic or inorganic substances can reduce DO, leading to anaerobic conditions and harming aquatic ecosystems.

Continuous monitoring of dissolved oxygen is crucial for maintaining healthy water bodies. The Daruifuno OPD790 sensor provides reliable and real-time DO measurements, enabling effective water quality management.

Why Choose the Daruifuno OPD790 Sensor?

• High Accuracy: ±0.1 mg/L DO content, ±1% saturation, ±0.5°C temperature.
• Wide Measuring Range: DO: 0.00~20.00 mg/L, Saturation: 0~200%, Temperature: 0~50°C.
• Fast Response Time: T90 <25s (0→100%), T90 <30s (100→0%).
• Plug-and-Play: No reagents or oxygen consumption required; easy integration with the MCC200 multi-parameter controller.
• Robust Design: IP68 protection grade; operates under 0~3Bar pressure and 0~50°C temperature.

Applications of the OPD790 Sensor

The Daruifuno OPD790 dissolved oxygen sensor is ideal for monitoring surface water in:

• Rivers and streams
• Lakes and reservoirs
• Fish ponds and aquaculture systems
• Industrial wastewater treatment plants

Pair it with the MCC200 multi-parameter controller to monitor dissolved oxygen, pH, turbidity, and conductivity simultaneously.

Understanding Dissolved Oxygen Supersaturation

Supersaturation occurs when DO levels exceed the saturation point under specific conditions (e.g., high temperatures, sunlight, eutrophic water bodies). While rare, it can indicate algal blooms or turbulent water flow.
