KWS-120 COD Sensor
Introduction
Based on the UV254 absorption method, the KWS-120 COD sensor reliably measures COD and turbidity in water. Multi-wavelength visible light absorbance combined with a patented algorithm effectively reduces interference from suspended solids in complex water environments. The sensor features an auto-cleaning brush with configurable cleaning modes for energy-efficient long-term deployment.
Features
- Sensitive and stable UV signal detection
- Dual-algorithm correction for suspended solids interference
- Multiple optical window cleaning modes for various deployment scenarios
- China and US patented technology with multi-parameter support
- Standard 4-wavelength configuration, expandable to 10-wavelength
- Digital RS485 output with MODBUS protocol
- 316L stainless steel housing (customizable)
- IP68 protection rating for submerged operation
Dimensions
O.D. 33 mm, NPT 3/4 inch thread. The sensor is designed for easy installation via standard pipe fittings and supports both immersion and flow-through mounting configurations.
