The Intelligent Spectral Analyser (lSA) is a compact UV/Vis spectrometer that allows the simultaneous determination of a variety of parameters with a single optical sensor. Through the evaluation of the entire absorption spectrum from the UV until the near-infrared range (200-720nm), water properties, contained suspended solids, as well as dissolved substances can be comprehensively characterized. It can be used for drinking water, wastewater, process measurement & control technology, environmental monitoring, etc.
