DO Sensor (Dissolved Oxygen Sensor) : The Heart of Modern Wastewater Treatment Systems

DO Sensor (Dissolved Oxygen Sensor) is a critical variable that determines success in aquaculture and wastewater management. Since DO (Dissolved Oxygen) levels directly impact ecosystems, this device is not just a common measurement tool—it is a core technology that enables real-time monitoring to maintain optimal water balance.
E-Power Service Co., Ltd., a leader in industrial technology, presents high-standard DO Sensor solutions. Our technology transforms traditional water management into an automated system that is precise, cost-effective, and elevates your operations to a professional level.
What is a DO Sensor? Why measure Dissolved Oxygen?
A DO Sensor is an electronic device used to measure the amount of gaseous oxygen dissolved in a liquid, which is vital for aquatic life:
- Aquaculture: If DO levels are too low, aquatic animals suffer from stress, become weak, or die. Using sensors allows for immediate alerts and triggers aerators to start instantly.
- Wastewater Treatment: It helps control the amount of air required in treatment tanks, ensuring microbes function efficiently while reducing electricity costs by avoiding unnecessary aeration.
Leading DO Sensor Brands Trusted by E-Power Service
To meet diverse operational needs, we recommend two world-class brands with outstanding technology:
1. RIKA SENSOR: Model RK500-11 (Industrial Durability)
Designed for heavy-duty industrial use and general aquaculture. The housing material is corrosion-resistant, easy to install, and provides long-term stability.
2. SUPMEA (SUP): Model SUP-DM2800 (Advanced Optical Technology)
SUPMEA (or SUP) stands out with its Fluorescence Method (Optical DO Sensor), a breakthrough innovation:
- Membrane-Free: No electrolyte solution required, making it easy to maintain and reducing long-term costs.
- High Precision & Speed: Stable measurements with no flow requirement, providing rapid and accurate responses.
- Anti-Interference: Excellent resistance to external light and chemicals, ideal for wastewater systems requiring high precision.
Elevate Water Management with E-Power Service Solutions
Every sensor we select features professional-grade capabilities:
Pro-Level Accuracy: Built-in Temperature Compensation ensures steady readings despite water fluctuations.
Versatile Connectivity: Supports 4-20mA and RS485 (Modbus RTU), allowing seamless
connection to PLCs or IoT Gateways for cloud-based data access.
High Durability: IP68 waterproof rating, suitable for long-term submersion with minimal maintenance.
Conclusion: Boost Productivity and Reduce Costs with Data
Installing a DO Sensor from RIKA or SUPMEA, integrated with E-Power Service automation, is a worthwhile investment. It provides 24-hour insights, reduces the risk of crop loss, and significantly saves on electricity through smart aeration management.
