Global Water EZ100 Sensor Display
All of Global Water's electronic sensors seamlessly interface to the EZ100 Sensor Display, which can be used for both portable and permanent installations. Global Water's EZ Display features a large LCD readout that can be configured to display 4-20mA electronic sensor output values in any engineering units. The portable display is housed in a rugged, weatherproof enclosure that can be either hand held or wall mounted.

WTW IQ Online Monitoring System
The IQ Sensor Net system is the most flexible, digitally based online system that provides from 1 to 20 measuring points. The module based system allows you to "grow" your system as your conitnuous water quality monitoring needs change.
For the measuring and control of wastewater, WTW offers the world's most complete line of pH/ORP, D.O., Conductivity, Nitrogen, Carbon, Phosphate, and unique self-cleaning Turbidity instrumentation, as well as comprehensive accessories.

WTW IQ SensorNet 2020 XT Controller
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.

WTW IQ Sensor Net DIQ/S 282/284 Controller
The new WTW DIQ/S 282/284 (2 and 4 channel) controller replaces the DIQ/S 182 from June 2016
The new controller is for small and mid-sized wastewater treatment plants and includes a USB-interface with an internal data logger - up to 4 sensors can be connected and 20 parameters measured siumultaneously.

WTW UV 700 IQ SAC
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.

WTW VisoTurb® 700 IQ & ViSolid® 700 IQ Sensors
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 Online Dissolved Oxygen (DO) Measurement
WTW has been continuously designing, manufacturing and satisfying the demands for reliable dissolved oxygen measurements with the most advanced online systems available anywhere.
