Next Generation of Online Water Quality Sensors

ITT Corporation (USA) has announced the introduction of the next generation of WTW spectral sensors CarboVis®, NitraVis® and NiCaVis® for use with the WTW IQ SensorNet System for online measurements including COD, BOD, TOC and TSS in wastewater applications. ITT Analytics will showcased its WTW spectral sensors during WEFTEC 2011 in Los Angeles, USA.

The new optical system design ensures measurement accuracy, repeatability and stability. The drift-free sensor guarantees reliable data over extended periods of time, without the need for routine maintenance. Using the full UV-VIS spectral wave length range from 200 to 720 nm provides the best measurement results and optimum compensation of interferences like turbidity.

The integrated, advanced ultrasonic cleaning system reduces manual window cleaning to an absolute minimum. High performance materials including Titanium and PEEK are used to withstand harsh conditions for extreme durability over the entire sensor lifespan.
