  • Description
    Digital, optical sensor for the IQ SENSOR NET
    NiCaVis® 700 IQ NI: UV probes with integrated ultrasonic cleaning for the reagent-free measurement of nitrate, nitrite and carbon parameters directly in the process:
    •Measurement directly in the process
    •No waiting for response times
    •Maintenance-free WTW ultrasonic cleaning
    •No wear parts, like wipers
    •Now available for surface water
    The full flexibility for your measurement:
    The high resolution of these sensors allows the precise distinction and measurement of nitrate and nitrite. At the same time, up to 3 carbon parameter such as COD, BOD, DOC, TOC, UVT or SAC are determined. This allows the complete monitoring and optimization of processes in the aeration of wastewater treatment plants.
