NiCaVis® 70x IQ TS

Digital, optical sensor for the IQ SENSOR NET
NiCaVis® 705 IQ: Sensor with integrated ultrasonic cleaning for the reagent-free measurement of nitrate, carbon parameters and TSS in the wastewater treatment system drain:

  • Reagent-free measurement of NO3, COD, BOD, TOC, DOC, SAC, UVT, TSS
  • 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 and suspended solids 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.

NitraVis®700 IQ NI: Sensor with maintenance-free ultrasonic cleaning for measurement of nitrate and nitrite directly in the process – optimized for municipal wastewater treatment systems:

  • High measuring accuracy
  • Easy handling
  • Minimal operating costs
    High measuring accuracy
    The innovative spectral measuring technique of these sensors allows the determination of nitrate and nitrite directly in the process. Based on the measurement of the entire spectrum, cross sensitivities of individual parameters among each other and interference such as turbidty are eliminated effectively. This ensures highly precise and reliable measuring results!

Easy handling
Based on the optical method, time-consuming steps such as sampling and sample preparation are eliminated. This also eliminates waiting for response time, which allows for a nearly continuous measuring process. This makes measured values available quickly and without complications.

Minimal operating costs
Spare parts such as wiper profiles and seals are not necessary thanks to the maintenance-free ultrasonic cleaning. The use of a chemical-free measuring method further reduces operating costs to a minimum.
