WTW NitraVis 701-705 IQ (TS)

NiCaVis® 701/705 IQ NI

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. 

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.
