  • Description

    Digital, optical sensor for the IQ SensorNet

    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.
