Electro-chemical IQ sensors for dissolved oxygen
TriOxmatic® IQ: Reliable and proven digital electro-chemical oxygen sensors with 3 electrode system (ECDO) for precise and accurate measurements
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.

TriOxmatic® IQ: Reliable and proven digital electro-chemical oxygen sensors with 3 electrode system (ECDO) for precise and accurate measurements

IQ optical spectral probes (UV-VIS) for carbon parameters and suspended solids
Optimal for the measurement of TOC and DOC in the inlet/effluent of municipal wastewater treatment plants.

LAR’s QuickTOCultra continually checks the TOC content of waste water. Optionally, other sum parameters can be detected aswell. At 1,200 °C,msamples are completely oxidised and within 3 minutes the TRUE TOC result is determined.

photometric analyzer with large measuring range and a high resolution for free and total chlorine with the DPD method according to the ISO and US EPA.
