Desun Uniwill DS502 TOC Sensor, 0-1000mg/l, RS485 Output, IP68 Immersion Probe
The Desun Uniwill DS502 is an immersion-type TOC sensor with RS485 Modbus output, designed for continuous, reagent-free monitoring of organic load (COD, BOD, TSS, TOC) in industrial wastewater and effluent streams. It integrates directly with SCADA, PLCs, and data acquisition systems via its digital interface.
Features
- Reagent-free UV absorption measurement (254 nm UV + 850 nm IR) for low-maintenance operation.
- Digital RS485 Modbus RTU output for seamless network and SCADA integration.
- Rugged IP68-rated immersion probe constructed from SS316 or titanium alloy.
- Automatic turbidity compensation and integrated self-cleaning brush mechanism.
- Wide dynamic range suitable for high-load industrial wastewater applications.

The DS502 online sensor utilizes a dual-wavelength UV absorption principle (254 nm UV and 850 nm IR) to measure Total Organic Carbon (TOC) and related parameters like COD and BOD without requiring chemical reagents. Its narrow 2mm optical path is optimized for higher concentration ranges, while automatic turbidity compensation ensures stable readings in varying water clarity.
Engineered for harsh industrial environments, the probe features a robust SS316 or titanium alloy housing with an IP68 waterproof rating, capable of withstanding immersion pressures up to approximately 1 bar. The integrated self-cleaning brush mechanism minimizes fouling, supporting long-term deployment with minimal maintenance in wastewater treatment plants, industrial effluent monitoring, and environmental surveillance networks.
