WTW NitraVis 701-705 IQ (TS)

NitraVis 701/705 IQ (TS)

Digital, optical sensor for the IQ SENSOR NET
NitraVis® 700 IQ (TS): Sensor with integrated ultrasonic cleaning for the reagent-free measurement of nitrate and suspended solids (optional) – optimized for municipal wastewater treatment systems.

Spectral measurement of nitrate and suspended solids content without chemicals for all applications needing an accurate nitrate measurement.

The integrated WTW ultrasonic cleaning prevents the attachment of deposits from the very beginning. This ensures comparable and reliable measured values in continuous operation.
