RENKE dissolved oxygen meter electrode + controller

Product Features

• Complete Out-of-the-Box Monitoring System
• A fully integrated kit combining an industrial-grade Intelligent Controller box with a high-performance Optical DO Electrode, eliminating any hardware compatibility worries for rapid field deployment.
• Advanced Graphic Display & Interface
• The premium controller features a bright, multi-data backlit digital display that simultaneously reads out Dissolved Oxygen levels (6.48 mg/L), percentage saturation (0–200%), real-time liquid temperature (°C), and output loop current (mA).
• Zero-Maintenance Fluorescence Optical Technology
• Utilizes cutting-edge optical lifetime sensing that does not consume oxygen during analysis. It operates perfectly without internal membrane caps or consumable electrolyte fluids, cutting down maintenance costs to near-zero.
• Ultra-Rugged 316 Stainless Steel Probe
• The fluorescence DO electrode is heavily armored in a solid 316 Stainless Steel casing, providing premium protection against corrosion, severe mechanical impacts, and continuous deep-water submersion.
• Precision Auto Temperature Compensation (ATC)
• Continuously tracks solution temperature shifts to actively fine-tune and balance the dissolved oxygen data live, preventing measurement drift or false saturation alarms during hot days or freezing nights.
• Anti-Interference RS485 Modbus Protocol
• Communicates using standard Modbus RTU over RS485 (DC 10-30V power), completely isolating the data stream from heavy electrical feedback caused by nearby paddlewheels, commercial aerators, or factory motors.
• Smart Dosing & Automation Ready
• The master controller box features programmable internal menu keys and signal outputs, allowing you to seamlessly link with PLCs, SCADA networks, or external aeration relays to turn on oxygen pumps automatically when levels drop too low.
