Product Description

Ultraviolet Fluorescence Analysis Theory Online COD Meter Sewage River COD Online Monitoring



  • Many organic compounds dissolved in water attract UV light. It is therefore possible to measure the total amount of organic contaminants in water by measuring the ultraviolet absorption of these organics at a wavelength of 254nm.
  • The DSC5001 series sensors use two light sources, one at 254nm UV and one at 850nm IR, which enables automatic compensation for light path degradation and turbidity effects, leading to more stable and stable measurement values.



  1. Digital sensor, RS-485 output, MODBUS
  2. No reagents, pollution-free, more cost effective, more eco-friendly
  3. Measure COD, BOD, TSS and other parameters
  4. Excellent testing performance with automatic compensation for turbidity interference
