With an easily scalable solution, the 2020 XT allows for the connection of up to 20 sensors. This modular plug-and-play system allows you to monitor the water quality in your wastewater system continuously and accurately.
The CarboVis® is a reagentless, optical-based spectrophotometer built into a rugged, corrosion-resistant field probe for the IQ SensorNet system. The CarboVis can report up to 5 parameters including: COD (total and soluble), BOD, UVT-254, TOC, DOC, SAC (total and soluble) and TSS (optional).
The SAC sensor measures Spectral Absorption Coefficient (SAC) and UV transmission (UVT) at 254nm for determination of organic loads in water. With the sensor UV 700 IQ SAC this parameter can be detected directly without any chemicals. A reference measurement is performed for compensation of turbidity influences.
With the VisoTurb® 700 IQ and ViSolid® 700 IQ sensors, WTW presents a family of optical sensors for turbidity and suspended solids measurement. These sensors incorporate a ultrasound cleaning system that guarantees low maintenance and long-term reliability of the sensors. Turbidity measurements in aqueous media with VisoTurb® are carried out nephelometrically in compliance with EN ISO 7027. Solid matter measurement with ViSolid® is performed according to the principle of scattered light measurement.
WTW has been continuously designing, manufacturing and satisfying the demands for reliable dissolved oxygen measurements with the most advanced online systems available anywhere.
The new multi-parameter systems with intelligent, digital sensors for pH, dissolved oxygen (DO) and conductivity measurement revolutionize multi-parameter measurement:
The signal processing is completely located in the sensor, and the measuring signal is transmitted to the meter without interference and in a clearly identifiable manner via thin, highstrength cables. A wide range of sensors are available for virtually every application.
