Optical and electro-chemical sensors for the measurement of dissolved oxygen with analog monitors or the modular and flexible IQ Sensor Net
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.
For continuous pH/ORP measurement, especially under the difficult conditions very often found in sewage treatment facilities, very high demands are made concerning the reliability and operating safety of the systems employed.
Application oriented benchtop sets for multiple parameter monitoring: pH, mV, ISE, saturation, concentration, partial pressure, conductivity, special resistance, salinity, TDS, temperature
Cutting edge technology from WTW for demanding laboratory applications. Two digital inoLab® multi-parameter instruments for IDS sensors for parallel measuring of one identical or varying parameters. Up to three sensors (inoLab® Multi 9430 IDS) can be connected. A large glass shield protects the graphic display and supports the presentation of the measuring values and recognition of important information. The innovative and antibacterial keypad helps to protect against microbiological contamination. The solid zinc die-casting lower case gives the meters a safe standing and also protection from the environment. As a special feature, both models can be upgraded with an additional module for conventional pH measurement.
The inoLab® family: Advanced measuring technology offers new functions including automatic AutoRead or CMC (Continuous Measurement Control) making measurements more convenient and reliable than ever.
The user interface, large display and keypad with tactile feedback provide an exceptional user experience and error-free operation.
All benchtop meters are available in application oriented sets including sensors and accessories.
OxiTop® systems for BOD or other depletion / respiration applications
- Complete packages ready to use
- Simple, flexible, secure, compliant, customisable and scalable

The optimum solution to support phosphate elimination as well as monitor phosphate freight - on-site analyzer for orthophosphate measurement in the IQ Sensor Net
The VARiON probe is used within the IQ SensorNet system and can therefore be networked with other probes and parameters for a complete process monitoring and control system. It can measure, report and control off of the ammonium and/or nitrate measurements with automatic compensation for potassium (for ammonium) or chloride (for nitrate).
The IFL is an ultrasonic, interface level measurement sensor for the IQ SensorNet system. During the wastewater treatment process, the measurement of the interface level between liquids is of vital importance for optimal performance and trouble-free operation. The 700 IQ IFL provides continuous data to help operational efficiency improvement decisions. Simply connect it to the IQ SensorNet system.
