Renke RS-LDO-N01-2-20 Dissolved Oxygen Sensor, 0~20mg/L, IP68, RS485 Modbus, 5m Cable
The Renke RS-LDO-N01-2-20 is a fluorescence-based dissolved oxygen sensor designed for continuous water quality monitoring. It features a wide 10-30V DC power input, RS485 Modbus output for direct integration with PLCs, SCADA systems, or data loggers, and includes automatic temperature compensation for accurate readings across a 0-40°C operating range.
Features
- Fluorescence-based measurement principle for zero oxygen consumption and no electrolyte required.
- Wide 0-20 mg/L (0-200% saturation) measurement range with ±3% FS accuracy.
- Integrated RS485 Modbus communication with configurable address and baud rate.
- Robust IP68-rated housing with POM and stainless steel construction for harsh environments.
- Includes automatic temperature compensation with ±0.5°C accuracy at 25°C.

The RS-LDO-N01-2-20 dissolved oxygen sensor operates on the fluorescence quenching principle. A fluorescent cap is excited by an internal LED, and the intensity and decay time of the returning fluorescence, which is inversely proportional to dissolved oxygen concentration, is measured. This method eliminates the need for membranes, electrolytes, or stirring, providing stable, maintenance-free operation.
The sensor incorporates a high-precision temperature probe for real-time automatic compensation, ensuring measurement accuracy is maintained across varying water conditions. Its wide 10-30V DC input and Modbus RTU protocol output make it compatible with industrial automation systems, environmental monitoring stations, and custom IoT platforms for remote data acquisition and control.
