ABB supplies the semiconductor, solar cell and flat panel display industries with the first in-situ, real time, non-contact analyzer for wet bench monitoring. ABB is not only a global leader in real time measurements for process control but the leading supplier of fiber optic multi-bath FT-NIR instrumentation to the electronics and solar power industries. 

With numerous standard calibrations and a scientific staff dedicated to custom applications, the ABB Wet Process Analyzer has been installed in over a thousand baths worldwide. The WPA is the only analyzer with a lifetime warranty on its optical “engine:” this is a robust, stable, low maintenance analyzer providing unsurpassed results. When the WPA shows a property trending up or down, it is a real trend not analyzer drift.
