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.
