UV RS485 COD Sensor IP68 Water Quality Monitor 0.15-1000mg/L Range with RS485 Output
The UV RS485 COD Sensor provides precise chemical oxygen demand measurement using advanced UV absorption technology. This industrial-grade sensor delivers reliable water quality monitoring with IP68 protection for demanding environments.
The COD sensor utilizes UV254 nano-ultraviolet absorption technology to detect organic pollutants. By measuring absorption at 254nm wavelength and compensating with 550nm light source, it effectively eliminates turbidity and chromaticity interference for stable, accurate readings without chemical reagents or consumables.
- Imported UV LED cold light source with minimal drift and extended lifespan
- No sample digestion required - rapid analysis without chemical reagents
- Drop-in installation with quick real-time response - no waiting periods
- Integrated automatic cleaning brush prevents contamination buildup
Wastewater treatment plant outlets, natural water monitoring, industrial process control, aquaculture systems, and drinking water quality assessment.
