RENKE dissolved oxygen electrode

Product Features

• Advanced Fluorescence Optical Sensing
• Utilizes state-of-the-art optical lifetime technology that does not consume oxygen during measurement. It is completely independent of liquid flow rate, delivering highly accurate and stable readings even in dead zones or stagnant water.
• Heavy-Duty 316 Stainless Steel Housing
• The entire probe body is encased in premium, industrial-grade 316 Stainless Steel. This ensures exceptional resistance to rust, impact, and corrosion, making it perfect for long-term submersion in harsh aquaculture or wastewater conditions.
• Zero-Maintenance & Membrane-Free Design
• Unlike traditional polarographic sensors, this optical probe requires no electrolyte fluids and no consumable membranes. This completely eliminates routine servicing and lowers your long-term cost of ownership.
• Anti-Interference RS485 Communication
• Equipped with a built-in RS485 Modbus RTU digital output. This provides 100% protection against electrical noise from high-power water pumps, paddlewheel aerators, and surrounding factory equipment.
• 0-20 mg/L Precision Detection Range
• Tracks dissolved oxygen levels with high sensitivity and accuracy. It features rapid response times, making it ideal for delicate aquatic ecosystems like shrimp hatcheries and fish farms where oxygen crashes must be prevented.
• Built-in Automatic Temperature Compensation (ATC)
• An integrated internal temperature sensor automatically adjusts and calibrates the DO readings live as the water warms up or cools down, ensuring uncompromised data accuracy 24/7.
• Plug-and-Play Automation Ready
• The digital Modbus protocol allows the probe to connect directly to standard PLCs, SCADA networks, smart IoT controllers (like ESP32/Arduino), or HMI displays without requiring an external transmitter box.
