The WTW program offers the world's most complete product line of pH, ORP, oxygen, BOD, respirometry and conductivity meters, turbidity meters and photometers including reagents. In addition to robust, waterproof portable meters, portable indestructible field meters, the product line also includes a complete series of benchtop meters and accessories as well as a multitude of completely newly developed state-of-the-art multiparameter devices for lab and field applications.

For the measurement and monitoring of water and wastewater, we offer the most complete series of measurement systems in the world for pH/ORP, oxygen, conductivity, nitrogen, carbon, phosphate and self-cleaning turbidity/suspended solids measuring technology as well as comprehensive accessories.

The reliability, operational safety and versatility of proven WTW measurement systems and analyzers have established WTW products as a global industry standard.

The IQ Sensor Net has been the standard for online measuring technology for years. It is suitable for conventional measuring technology with analog outputs as well as for field bus technology. The innovative digital sensors in this system reflect state-of-the-art technology.

The terminal/controller MIQ/TC 2020 XT is the extremely high-performance heart of every IQ sensor. The dual processor function inherent in every MIQ/TC 2020 XT increases system security and therefore the availability of the entire system. The integrated USB interface allows quick data exchange via USB stick or directly to external systems. The IQ Sensor Net 282/284 – the economical solution for up to four sensors - is especially suitable for central measuring points, i.e, for locations where several parameters have to be measured at the same site. For measuring points with only one parameter, the new system 181 with its fixed cable sensors is available for pH/ORP, oxygen, turbidity and conductivity – the low-costs alternative to analog measuring points. This makes the IQ Sensor Net the most flexible multi-parameter system for 1 to 20 measuring points that is based on digital technology.
