Online DO Sensors, Probes, Analyzers and Controllers
Dissolved oxygen sensors measure the oxygen concentration dissolved in water. In wastewater treatment, online DO sensors help control aeration, biological treatment stability and energy consumption. In aquaculture and environmental monitoring, DO probes help prevent low-oxygen stress and support continuous water quality observation. In pure water and boiler-related applications, low-range dissolved oxygen monitoring can be important for corrosion control and process stability.
LOOTEST can provide optical fluorescence dissolved oxygen sensors, polarographic DO probes, dissolved oxygen analyzers and controller matching options according to water type, measuring range, temperature, installation position and maintenance plan. Online DO sensors can be integrated with RS485 Modbus, 4-20mA, relay output, PLC, SCADA, aeration blowers, dosing control and OEM water quality monitoring equipment.
Dissolved Oxygen Sensor Applications
Wastewater Aeration Control
Use online DO sensors to monitor aeration tanks, activated sludge, biological treatment efficiency and aeration energy control.
Aquaculture and Environmental Water
Track dissolved oxygen levels in fish farms, ponds, rivers, lakes, reservoirs and outdoor monitoring stations.
Drinking Water and Process Water
Add DO measurement to drinking water, process water and treatment systems where oxygen level affects water stability.
Pure Water and Industrial Systems
Monitor low dissolved oxygen in boiler feed water, condensate, ultrapure water and industrial process control projects.
How to choose an online dissolved oxygen sensor supplier
For B2B purchasing, dissolved oxygen sensor selection should start with the application: wastewater aeration, aquaculture, environmental monitoring, drinking water, process water or pure water. Then confirm the measuring range, required accuracy, water temperature, installation method, cleaning frequency, cable length and output signal. A reliable online DO sensor should match both the oxygen measurement task and the maintenance conditions of the site.
- Wastewater treatment: choose a DO sensor suitable for aeration tanks, activated sludge, biological treatment and frequent cleaning conditions.
- Aquaculture: select a dissolved oxygen probe with stable response for ponds, tanks, fish farms and continuous outdoor monitoring.
- Environmental monitoring: use optical DO sensors when low maintenance, long-term field deployment and remote data collection are important.
- Pure water and boiler systems: check whether ppm-level or ppb-level dissolved oxygen measurement is required before choosing the analyzer.
- Automation projects: confirm RS485 Modbus, 4-20mA, relay output and controller compatibility for PLC, SCADA or cloud monitoring systems.
FAQ for dissolved oxygen sensors and B2B supply
What does a dissolved oxygen sensor measure?
A dissolved oxygen sensor measures the amount of oxygen dissolved in water. It is commonly used in wastewater treatment, aquaculture, environmental monitoring, drinking water, process water and pure water systems.
What is the difference between a DO sensor and a DO analyzer?
A DO sensor or probe is the measuring part in contact with water. A dissolved oxygen analyzer usually includes the sensor plus a transmitter, controller or display unit for signal processing and data output.
Should I choose an optical dissolved oxygen sensor?
Optical fluorescence DO sensors are often selected for wastewater, aquaculture and environmental monitoring because they usually require less maintenance and do not consume oxygen during measurement.
When is a polarographic dissolved oxygen probe suitable?
Polarographic DO probes can be suitable for stable industrial water, pure water or analyzer-based applications when the project requires a specific measurement principle, range or controller configuration.
Can DO sensors connect to PLC or SCADA?
Yes. Depending on the selected model and controller configuration, LOOTEST dissolved oxygen sensors can support RS485 Modbus, 4-20mA or relay output for PLC, SCADA, aeration control and remote monitoring systems.
Can dissolved oxygen monitoring reduce aeration cost?
In wastewater treatment, online DO monitoring can help operators adjust aeration intensity according to real oxygen demand, which may support process stability and energy management.
