Dissolved oxygen (DO) is one of the most important parameters for understanding water quality. Whether in aquaculture, wastewater treatment, environmental monitoring, or industrial water systems, maintaining the right oxygen level can directly affect water conditions, biological processes, and overall system performance.
The DO800D Online Optical DO Sensor provides a reliable solution for continuous dissolved oxygen monitoring, helping operators obtain accurate measurements and make better-informed decisions.
What Is the DO800D?
The DO800D is an online optical dissolved oxygen sensor designed for continuous monitoring of dissolved oxygen and temperature in water.
Unlike manual testing methods that require operators to collect samples and take measurements periodically, an online sensor can remain installed within the monitoring system, providing consistent measurements without requiring frequent manual intervention.
Its optical sensing technology is designed for stable and reliable measurement, making it suitable for applications where continuous water-quality information is important.
Why Is Dissolved Oxygen Monitoring Important?
Dissolved oxygen affects many aquatic and water-treatment processes.
In aquaculture, adequate oxygen levels are essential for fish and shrimp health and growth. Low DO can create stressful conditions and negatively affect production.
In wastewater treatment, oxygen is an important factor in biological treatment processes. Monitoring DO allows operators to better understand and control oxygen conditions within treatment systems.
For lakes, rivers, reservoirs, and other environmental applications, DO measurements can provide valuable information about overall water conditions and changes in aquatic environments.
Continuous monitoring helps users identify changes in oxygen levels before they become larger operational problems.
Key Features of the DO800D
1. Continuous Online Monitoring
The DO800D is designed for continuous measurement, allowing operators to monitor dissolved oxygen conditions without relying solely on periodic manual sampling.
2. Optical Dissolved Oxygen Measurement
The optical sensing method provides stable DO measurement and is designed for reliable long-term monitoring with reduced routine maintenance requirements.
3. Wide Measurement Range
The sensor measures dissolved oxygen from:
0–10 ppm
It also measures water temperature from:
0–45°C
This makes it suitable for a variety of water-monitoring environments.
4. Reliable Accuracy
The DO800D provides:
- DO accuracy: ±3% of measured value
- Temperature accuracy: ±0.5°C
Reliable measurements can help operators make more informed decisions about water treatment, aeration, and system operation.
5. Modbus RS485 Communication
The sensor uses Modbus RS485 communication, making it suitable for integration with compatible monitoring systems, controllers, PLCs, and other industrial equipment.
This allows measured data to become part of a larger water-quality monitoring and control system.
6. 10-Meter Cable
The DO800D comes with a 10-meter cable, providing flexibility for installation in tanks, treatment systems, ponds, and other water-monitoring locations.
Applications
The DO800D can be used across several industries:
Aquaculture
Monitor dissolved oxygen levels in fish and shrimp farming systems to help maintain suitable water conditions.
Wastewater Treatment
Track DO levels in treatment processes where oxygen availability is important for biological treatment.
Environmental Monitoring
Monitor oxygen conditions in lakes, rivers, reservoirs, and other natural water environments.
Industrial Water Systems
Provide continuous DO data for industrial processes where water quality needs to be monitored and controlled.
Surface Water Monitoring
Measure dissolved oxygen in water bodies to support ongoing water-quality assessment.
