Digital optical UV-VIS spectral sensor for nitrate and carbon parameters like COD

WTW sensors - optical UV-VIS spectral sensors (nitrate, COD) NiCaVis® 705 IQ

NiCaVis® 705 IQ: Sensor with integrated ultrasonic cleaning for the reagent-free measurement of nitrate and carbon parameters in the wastewater treatment system drain

  • Reagent-free measurement of NO3, COD, BOD, TOC, DOC, SAC, UVT
  • No wear parts
  • Extremely robust thanks to titanium and PEEK

The optical measuring method of these sensors allows continuous measuring of carbon and nitrogen parameters directly in the medium. With this procedure, the information of the entire spectrum is evaluated, which allows the simultaneous determination of multiple parameters. At the same time, cross sensitivities of individual parameters among each other and interference such as turbidty are eliminated.
