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.
