WTW UV Sensors for Nitrate

UV 700 IQ NOx: Low-cost probe with integrated ultrasonic cleaning for the maintenance-free and reagent-free measurement of nitrate:
•No replacement of seals or wiper profiles
•Minimal effort thanks to maintenance-free WTW ultrasonic cleaning
•No danger of emerging water thanks to completely sealed housing
•No corrosion thanks to titanium housing
With the new sensor UV 700 IQ NOx, nitrate is detected via a UV absorption measurement at a wavelength below 250 nm. Turbidity influences are effectively compensated by a reference measurement. This cost-effective probe is especially suited to regulate or control intermittent aeration. Another field of application is the detection of nitrate in rivers.
