UV-VIS spectral sensors for nitrate (optional)

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:
• Optical procedures – no reagents
• Measurement directly in the medium
• Maintenance-free WTW ultrasonic cleaning
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.
